What is a PDA? Why buy a PDA? What are the
benefits of having a PDA? What
Types of PDA’s are available? Which PDA’s are
ranked the highest?
A PDA is a Personal Digital Assistant which basically
is a handheld computer. These mini-computers can
help you get organized fast. Use them in your
personal life or in your professional life. They come
in handy when you need information fast! So what
specifically can you do with a PDA? You can take
notes, look up a phone number, write and send email
and so much more. Specifically, most PDA’s have
the following features and benefits: Wireless internet
- Datebook--This is most important part of the
organizer. You can input meetings, appointments,
etc., all in basically the same format as a large, bulky
Day Planner. Memo Pad--A place to jot notes, write a
book, whatever. Calculator--Math. To-Do List--Helps
you accomplish those nagging tasks. Address
Book--Keeps track of all your important contacts.
OnScreen Keyboard--Lets you type with the touch
screen and your stylus. Grafitti(Palm)/Character
Recognizer(Pocket PC)--Lets you handwrite instead
of type. Email--Lets you compose email and send on
HotSync or wireless. Backlight (most PDAs)--
Priceless in dim lighting. PMBBAY recommends
CNET.COM for the latest and greatest in Tech News.
According to CNET, the right PDA handheld has to
be small enough that you enjoy toting it around, but
the battery needs to be big enough that it has some
juice left when you need it; plus, it must have a
decent-size screen. The variety of PDA handhelds
for sale these days attests to the fact that there isn't
one ideal design. Here are the features to consider.
Want to buy
a PDA handheld computer?
As PDA handhelds have evolved, their overall size
hasn't changed dramatically. Most current models
are between 4 and 5.5 inches long and about 3
inches wide, and they weigh between 4 and 7
ounces. Examples of extremely compact PDAs are
the HP iPaq rx1950 and Palm Z22, while on the other
side of the spectrum, you'll find handhelds such as
the HP iPaq hx4700. Ideally, they should ride
comfortably in a coat pocket or a purse and have a
screen large enough for on-the-go viewing. To
determine if the size and shape of a particular PDA
works for you, take a trip to your local retailer, as you
can't know for sure based on the published specs.
You'll want to see how it feels in your hands--light or
heavy, sturdy or fragile--and if you're comfortable
with the button layout for one-handed navigation.
Want to buy a PDA handheld computer?
PDAs with monochrome screens are definitely on
the decline as color models proliferate. For bargain
shoppers, the monochrome screen still might be an
option. Even so, entry-level models, such as the
Palm Z22, now incorporate color screens.
Color displays are easier to read, thanks to their
higher contrast ratio, and they're a must for viewing
digital photos and other multimedia functions. Pay
attention to screen resolution; all Windows Mobile
handhelds will have at least 240x320-pixel
resolution. You can still find Palm devices with
160x160 resolution, but our recommendation is to
opt for a model with at least 320x320 pixels.
Regardless of which OS you choose, selecting a
model with higher resolution shows off images to
their best effect. Want to buy
a PDA handheld computer?
Another consideration is the screen's performance
in sunlight. The first color screens were practically
illegible outdoors, but newer liquid-crystal displays
(LCDs) have solved the problem. In particular,
transflective thin-film transistor (TFT) screens are
one of the best performers indoors and out, due to
their reflective properties, which cause sunlight to
bounce off the screen. For indoor use, a backlight
provides illumination indoors or in the dark but
drains battery life. Want to buy
a PDA handheld computer?
PDAs typically have their operating system stored in
ROM (read-only memory) and use built-in RAM
(random access memory) for processor memory and
as file storage space; thus, while you're shopping,
pay attention to how much RAM is installed in the
device. As the name implies, ROM can only be read
and is nonvolatile, so data won't be lost if the
handheld loses power. On the other hand, RAM is
used for temporary storage of data to optimize
performance. Every handheld has more than enough
memory for basic handheld tasks. Models such as
the Palm Zire 31 come with a minimum of 16MB of
RAM, which can still store thousands of contacts
and calendar entries, with room for additional
programs. Want to buy a PDA handheld computer?
Throwing multimedia apps into the mix, however,
requires more RAM but not necessarily huge
amounts, so long as you seek a handheld with an
expansion slot. Handhelds support three kinds of
expandable memory: Sony's Memory Sticks (if you
still have an old CLIE), CompactFlash cards, and
MMC/SDIO media. Store PIM data, applications, and
other small files on the PDA's internal RAM, and
leave some space for processor headroom. You
don't want to jam 31.5MB of data onto a handheld
with 32MB of RAM. The handheld will slow to crawl,
taking a noticeably longer time to launch apps or
open files. Instead, keep your MP3s, video files, and
other big files on a memory card.
If you intend to use your PDA primarily as an
electronic day planner and, occasionally, an MP3
player, 16MB of memory will suffice. Multimedia
buffs, gamers, and those who like to crunch
databases on the go should opt for models with at
least 32MB. Palm devices that support MP3 playback
are available with between 16MB and 256MB of built-
in memory, while Windows Mobile devices run all the
way up to 128MB. Even then, you can't store a
plethora of MP3 files on the device. Want to buy
a PDA handheld computer?
Looking to the future, Palm blazed a new trail when it
introduced the LifeDrive with its integrated 4GB hard
drive, providing ample storage for all your work files
and digital entertainment. And now, with Windows
Mobile 5.0 and its support for hard drives, it's just a
matter of time before the technology is integrated
into Pocket PCs.
One final note on RAM: Some PDA models have a
portion of the built-in RAM dedicated to the operating
systems and other manufacturer-installed data. For
example, you may see a handheld advertised with
16MB of RAM, but only 12MB are available for data
storage. In our hands-on reviews, we try to identify
models where this is the case.
Like desktop PCs, a handheld with a fast processor
is critical for tasks such as playing games, music,
and videos or for sifting through large amounts of
data quickly. Palm OS devices with multimedia
features or integrated wireless communications use
a variety of processors from Intel, Motorola, Sony,
and Texas Instruments and are available with
maximum clock speeds of between 127MHz and
400MHz. The slower models will satisfy those who
use their PDA for Day Runner tasks and don't mind
waiting a second after snapping a digital photo.
Windows Media for Pocket PC handhelds use
StrongARM or XScale processors with maximum
clock speeds of between 200MHz and 624MHz. For
wirelessly streaming video to a Pocket PC and other
processor-intensive tasks, the faster models are
better choices. Want to buy a PDA handheld
computer?
All the latest processors regulate clock speed and
power consumption based on processor load; this
way, they extend battery life while improving
performance. But keep in mind that faster
processors tend to consume a bit more power, thus
reducing battery life.
Like any mobile gadget, a PDA is only as useful as
its battery life. When levels are low, the PDA is just
weighing you down. On some models, you also risk
losing data if you completely run out of power.
Thankfully, you can typically turn your off PDA and
avoid this scenario. However, take the
manufacturer's published specs with a grain of salt;
we've found many claims to be highly optimistic.
Want to buy a PDA handheld computer?
There are a few dusty old models left on store
shelves that use standard alkaline batteries, but we
recommend rechargeable batteries (lithium ion,
nickel cadmium, or nickel metal hydride) since you
won't have to replace them after they die. Even
better, look for a PDA with a cell that is rechargeable
and user replaceable. You can then carry a spare or
swap it out for a higher-capacity unit, which typically
offers double the battery life.
In most cases, you use a handheld in minute-long
spurts, so it's easy to go several days on a single
charge. It's when you start listening to music,
watching videos, or connecting wirelessly to the
Internet that battery life is at risk. Some devices can
last only a couple of hours performing those tasks.
One solution is to select a model with
aforementioned user-replaceable batteries, though
some handhelds come with internal backup memory
to protect your information if the main cell dies. The
trade-off is that these models tend to be more
expensive and larger. Alternatively, pick a model that
comes with a compact wall plug, or buy a travel
charger if you're on the road a lot. Want to buy a PDA
handheld computer?
The various handwriting-recognition systems found
on PDAs have their pros and cons. Graffiti, Block
Recognizer, and Letter Recognizer all depend on
how well you adapt to the software's rules. If you do
that well, they are extremely accurate. Transcriber, a
system found on Windows Mobile, attempts to
recognize natural handwriting, but it's easily thrown
off by less than perfect script. If these options
frustrate you, call up the onscreen keyboard and tap
out a message one letter at a time with the tip of the
stylus. Want to buy a PDA handheld computer?
Handwriting recognition has its limitations, so there
are a number of handhelds with built-in QWERTY
keyboards. Those who adjust to the small keys can
bang out an e-mail quickly. For the best of both
worlds, buy an accessory keyboard
Wireless Connectivity
If you want your PDA simply for organization, you
may not need any special wireless connections. But
it seems like everyone today wants to stay
connected. Here are your options.
Infrared
Infrared (IR) ports are built in on most mainstream
handhelds and are useful for short-range (less than
30 feet), low-bandwidth data transfers, but you will
need a clear line of sight for the two devices to
communicate with each other, as with TV remote
controls. If your laptop has an IR port, for example,
you'll be able to synchronize without a cradle or a
cable--a particularly handy feature for road warriors.
And if your handheld is equipped with the proper
software, you can even use infrared to control your
TV and other home entertainment devices. Want to
buy a PDA handheld computer?
Bluetooth
This short-range radio frequency (RF) technology
operates on a 2.4GHz spectrum and allows PDAs to
communicate with other Bluetooth-enabled gadgets
such as some cell phones; thus, you can dial
numbers straight from your handheld's contact list
or use your cell phone as a modem to check e-mail.
You can also transfer files, print to a Bluetooth
printer, or sync with a Bluetooth-equipped computer.
Unlike IR, Bluetooth's RF signals can travel through
clothing and other barriers, meaning you can leave
your phone in your pocket and still be connected to
your PDA. If the handheld doesn't come with the
technology built in, Bluetooth cards are available for
the expansion slots--just be sure it supports Secure
Digital Input Output (SDIO), a mandatory feature
when using a Bluetooth SD card. Want to buy a PDA
handheld computer?
Wireless LAN networking
With a Wi-Fi-enabled handheld, you can connect
directly to the Internet at high speeds to check e-
mail, browse the Web, and even access servers via
secure virtual private network (VPN) connections.
Like Bluetooth, Wi-Fi runs on a 2.4GHz spectrum,
and you need to be near (typically 75 to 300 feet
from) an access point in order to connect. If your
PDA doesn't come with built-in Wi-Fi, you can
purchase Wi-Fi networking cards to get connected.
Additionally, Wi-Fi requires a lot of power and
quickly drains most PDA batteries. Want to buy a
PDA handheld computer?
The majority of handhelds use the 802.11b standard,
which is the same one found in most common public
hot spots, such as cafes, businesses, and
universities; it also transmits info at a speed of
11Mbps. If you intend to connect to an 802.11a
network, which operates on a 5GHz frequency band
and has transfer rates of 54Mbps, you'll need to seek
out a card for your handheld's expansion slot.
Wi-Fi works great when you're close to a hot spot
but not if you wander far and wide. Instead, you
should consider handhelds that use cellular data
networks, although not a lot are currently available.
As with traditional cell phones, these provide broad
coverage, although you should expect more dead
spots in the data network than the voice network.
Smart phones typically employ this method to keep
the device connected. Alternatively, a Bluetooth PDA
with a separate data-capable cell phone can achieve
the same end. Downsides to consider are the fact
that you'll need to have a service contract with a
wireless provider, and download speeds are slower
than on a wireless LAN (115Kbps vs. 11Mbps).
There's a huge library of games for both Palm and
Windows Mobile (a.k.a. Pocket PC) devices, from
basic puzzle and word contests to first-person
shooters and real-time strategy titles. Sporting a
high-resolution VGA screen, a multimedia
accelerator, and a gaming bundle, the Dell Axim
X51v is a hot pick for gamers. We'll plug Download.

information on software. Want to buy

More and more PDAs today have built-in digital
cameras so that you can take snapshots on the fly.
Typically, handhelds have 1.2- or 1.3-megapixel VGA
cameras; you won't get the same image quality as
with a dedicated digital camera, but they're good if
you want to take a quick shot to e-mail to family or
friends. Want to buy a PDA handheld computer?
Even without a camera, you can transfer files from
your PC and convert your handheld into a portable
electronic photo album. The Palm LifeDrive even lets
you create slide shows with background music, and
Windows Media 2003 for Pocket PC Premium Edition
even comes with image-editing software for the PDA.
Want to buy
a PDA handheld computer?
Load up a memory card with tunes, and plug in
headphones--you've turned your organizer into an
MP3 player. If you have the Plus Digital Media
Enhancement for your Windows XP machine, you
can load your home videos onto your Pocket PC
device to watch anytime. Palm OS, too, supports
applications such as Kinoma Video Player to let you
watch videos you've downloaded to the device. One
note: Not all Palm OS handhelds have digital audio
and video players, so if having multimedia
capabilities is important to you, make sure to check
for audio/video support before purchasing the PDA.
Both Palm and Windows Mobile support e-book
readers. Reading on the screen of a PDA is naturally
a different experience from doing so on a paperback,
but a good story can pull you in, no matter what the
format. You should also take a look at services such
as AvantGo, which delivers Web sites to your
handheld or your smart phone for free. Each time
you sync, AvantGo will load the latest version of
your favorite Web sites such as the New York Times,
Rolling Stone, or CNET News.com. Want to buy a
PDA handheld computer?
Added applications elevate your handheld to being
more than a glorified Day Runner. We've already
mentioned Documents To Go as a tool for working
with spreadsheets and word-processing documents,
but there's also Margi's Presenter To Go so that you
can give PowerPoint slide shows right from your
handheld (it requires a VGA adapter). FileMaker,
among others, offers handheld database software,
and road warriors will appreciate expense-, time-,
and mileage-tracking software such as BillQuick
Palm and BillQuick CE that tie in with their office
billing and accounting software. Want to buy
a PDA handheld computer?
To keep from getting lost, try MapQuest-style
applications such as Mapopolis (alternatively, you
can use a Bluetooth GPS receiver add-on to navigate
to your destination). And once you've reached your
destination, you may still need help with the local
language; electronic phrase books such as
EasyTalk are ideal for the situation. Want to buy a
PDA handheld computer?
You'll find a variety of different expansion slot types
in PDAs: CompactFlash, SDIO, MultiMediaCard, Mini
SD, and Micro SD. A memory card is a great way to
store more applications and files as well as to back
up RAM data, which can be lost if your battery dies.
Other than the price per megabyte, all the form
factors are roughly equivalent.
Other expansion card options include Wi-Fi
networking cards, Bluetooth cards, digital cameras,
FM tuners, and bar-code scanners. Handhelds such
as the HP iPaq hx2750 have two expansion slots so
that you can simultaneously use a memory card and
a wireless networking card. As noted earlier, if your
PDA has an SD slot, see if it supports SDIO, a
necessary feature when using peripheral devices
rather than mere memory cards.
Handhelds endure rugged lives as they get tossed
from pocket to bag to desk. Some protection is in
order, but even pricey PDAs come with decidedly
cheap cases. If you know you're hard on your gear,
check out metal and rubber cases. For gentler folk, a
soft case is all you'll need--perhaps in leather to suit
your business attire. And don't forget the most
fragile component on your PDA: the screen.
Inexpensive plastic overlays are available to protect
it from scratches or inadvertent taps with a real pen
rather than the stylus. Want to buy a PDA handheld
computer?
Road warriors will need to have an extra battery for
their handheld, provided the handheld has user-
replaceable cells. When you miss a connecting flight
and have to call all your contacts to alert them of the
schedule change, it's no time to run out of power.
Likewise, heavy Wi-Fi users will appreciate the extra
juice. Want to buy
a PDA handheld computer?
If you don't have an extra cell or if your PDA's
batteries aren't user replaceable, then invest in a
travel charger. Most manufacturers supply wall
chargers with their devices, but some are too big to
ever leave the house. If you spend a lot of time in
your car, a car charger may be the best solution for
adding juice to your PDA.
Considering the multimedia prowess built into
handhelds, it's a shame that so many models come
with subpar earbud headphones--or none at all. The
good news is that many handhelds today come with
standard stereo jacks so that you can plug in better
'phones to really hear what your PDA can produce.
Some models, such as the Etymotic ER-6 Isolator,
are designed to passively block ambient noise so
that all you hear is the music. Still others feature
active noise cancellation, a technique that can
subdue outside sounds. Want to buy a PDA
handheld computer?
If you want to send e-mails from your PDA or take
notes during class, adding a keyboard is a good
option. There are several types to choose from: plug-
in minikeyboards to foldable models to ultracool
virtual keyboards. However, if you plan on typing out
a lot of e-mails or notes from your device, a handheld
with a built-in keyboard may be better suited to you.

weighing you down. On some models, you also risk
losing data if you completely run out of power.
Thankfully, you can typically turn your off PDA and
avoid this scenario. However, take the
manufacturer's published specs with a grain of salt;
we've found many claims to be highly optimistic.

There are a few dusty old models left on store
shelves that use standard alkaline batteries, but we
recommend rechargeable batteries (lithium ion,
nickel cadmium, or nickel metal hydride) since you
won't have to replace them after they die. Even
better, look for a PDA with a cell that is rechargeable
and user replaceable. You can then carry a spare or
swap it out for a higher-capacity unit, which typically
offers double the battery life.
In most cases, you use a handheld in minute-long
spurts, so it's easy to go several days on a single
charge. It's when you start listening to music,
watching videos, or connecting wirelessly to the
Internet that battery life is at risk. Some devices can
last only a couple of hours performing those tasks.
One solution is to select a model with
aforementioned user-replaceable batteries, though
some handhelds come with internal backup memory
to protect your information if the main cell dies. The
trade-off is that these models tend to be more
expensive and larger. Alternatively, pick a model that
comes with a compact wall plug, or buy a travel
charger if you're on the road a lot. Want to buy a PDA

The various handwriting-recognition systems found
on PDAs have their pros and cons. Graffiti, Block
Recognizer, and Letter Recognizer all depend on
how well you adapt to the software's rules. If you do
that well, they are extremely accurate. Transcriber, a
system found on Windows Mobile, attempts to
recognize natural handwriting, but it's easily thrown
off by less than perfect script. If these options
frustrate you, call up the onscreen keyboard and tap
out a message one letter at a time with the tip of the
stylus. Want to buy a PDA handheld computer?
Handwriting recognition has its limitations, so there
are a number of handhelds with built-in QWERTY
keyboards. Those who adjust to the small keys can
bang out an e-mail quickly. For the best of both
worlds, buy an accessory keyboard
Wireless Connectivity
If you want your PDA simply for organization, you
may not need any special wireless connections. But
it seems like everyone today wants to stay
connected. Here are your options.
Infrared
Infrared (IR) ports are built in on most mainstream
handhelds and are useful for short-range (less than
30 feet), low-bandwidth data transfers, but you will
need a clear line of sight for the two devices to
communicate with each other, as with TV remote
controls. If your laptop has an IR port, for example,
you'll be able to synchronize without a cradle or a
cable--a particularly handy feature for road warriors.
And if your handheld is equipped with the proper
software, you can even use infrared to control your
TV and other home entertainment devices. Want to
buy a PDA handheld computer?
Bluetooth
This short-range radio frequency (RF) technology
operates on a 2.4GHz spectrum and allows PDAs to
communicate with other Bluetooth-enabled gadgets
such as some cell phones; thus, you can dial
numbers straight from your handheld's contact list
or use your cell phone as a modem to check e-mail.
You can also transfer files, print to a Bluetooth
printer, or sync with a Bluetooth-equipped computer.
Unlike IR, Bluetooth's RF signals can travel through
clothing and other barriers, meaning you can leave
your phone in your pocket and still be connected to
your PDA. If the handheld doesn't come with the
technology built in, Bluetooth cards are available for
the expansion slots--just be sure it supports Secure
Digital Input Output (SDIO), a mandatory feature
when using a Bluetooth SD card. Want to buy a PDA
handheld computer?
Wireless LAN networking
With a Wi-Fi-enabled handheld, you can connect
directly to the Internet at high speeds to check e-
mail, browse the Web, and even access servers via
secure virtual private network (VPN) connections.
Like Bluetooth, Wi-Fi runs on a 2.4GHz spectrum,
and you need to be near (typically 75 to 300 feet
from) an access point in order to connect. If your
PDA doesn't come with built-in Wi-Fi, you can
purchase Wi-Fi networking cards to get connected.
Additionally, Wi-Fi requires a lot of power and
quickly drains most PDA batteries. Want to buy a
PDA handheld computer?
The majority of handhelds use the 802.11b standard,
which is the same one found in most common public
hot spots, such as cafes, businesses, and
universities; it also transmits info at a speed of
11Mbps. If you intend to connect to an 802.11a
network, which operates on a 5GHz frequency band
and has transfer rates of 54Mbps, you'll need to seek
out a card for your handheld's expansion slot.
Wi-Fi works great when you're close to a hot spot
but not if you wander far and wide. Instead, you
should consider handhelds that use cellular data
networks, although not a lot are currently available.
As with traditional cell phones, these provide broad
coverage, although you should expect more dead
spots in the data network than the voice network.
Smart phones typically employ this method to keep
the device connected. Alternatively, a Bluetooth PDA
with a separate data-capable cell phone can achieve
the same end. Downsides to consider are the fact
that you'll need to have a service contract with a
wireless provider, and download speeds are slower
than on a wireless LAN (115Kbps vs. 11Mbps).
There's a huge library of games for both Palm and
Windows Mobile (a.k.a. Pocket PC) devices, from
basic puzzle and word contests to first-person
shooters and real-time strategy titles. Sporting a
high-resolution VGA screen, a multimedia
accelerator, and a gaming bundle, the Dell Axim
X51v is a hot pick for gamers. We'll plug Download.

More and more PDAs today have built-in digital
cameras so that you can take snapshots on the fly.
Typically, handhelds have 1.2- or 1.3-megapixel VGA
cameras; you won't get the same image quality as
with a dedicated digital camera, but they're good if
you want to take a quick shot to e-mail to family or
friends. Want to buy a PDA handheld computer?
Even without a camera, you can transfer files from
your PC and convert your handheld into a portable
electronic photo album. The Palm LifeDrive even lets
you create slide shows with background music, and
Windows Media 2003 for Pocket PC Premium Edition
even comes with image-editing software for the PDA.
Want to buy

Load up a memory card with tunes, and plug in
headphones--you've turned your organizer into an
MP3 player. If you have the Plus Digital Media
Enhancement for your Windows XP machine, you
can load your home videos onto your Pocket PC
device to watch anytime. Palm OS, too, supports
applications such as Kinoma Video Player to let you
watch videos you've downloaded to the device. One
note: Not all Palm OS handhelds have digital audio
and video players, so if having multimedia
capabilities is important to you, make sure to check
for audio/video support before purchasing the PDA.
Both Palm and Windows Mobile support e-book
readers. Reading on the screen of a PDA is naturally
a different experience from doing so on a paperback,
but a good story can pull you in, no matter what the
format. You should also take a look at services such
as AvantGo, which delivers Web sites to your
handheld or your smart phone for free. Each time
you sync, AvantGo will load the latest version of
your favorite Web sites such as the New York Times,
Rolling Stone, or CNET News.com. Want to buy a
PDA handheld computer?
Added applications elevate your handheld to being
more than a glorified Day Runner. We've already
mentioned Documents To Go as a tool for working
with spreadsheets and word-processing documents,
but there's also Margi's Presenter To Go so that you
can give PowerPoint slide shows right from your
handheld (it requires a VGA adapter). FileMaker,
among others, offers handheld database software,
and road warriors will appreciate expense-, time-,
and mileage-tracking software such as BillQuick
Palm and BillQuick CE that tie in with their office
billing and accounting software. Want to buy

To keep from getting lost, try MapQuest-style
applications such as Mapopolis (alternatively, you
can use a Bluetooth GPS receiver add-on to navigate
to your destination). And once you've reached your
destination, you may still need help with the local
language; electronic phrase books such as
EasyTalk are ideal for the situation. Want to buy a
PDA handheld computer?
You'll find a variety of different expansion slot types
in PDAs: CompactFlash, SDIO, MultiMediaCard, Mini
SD, and Micro SD. A memory card is a great way to
store more applications and files as well as to back
up RAM data, which can be lost if your battery dies.
Other than the price per megabyte, all the form
factors are roughly equivalent.
Other expansion card options include Wi-Fi
networking cards, Bluetooth cards, digital cameras,
FM tuners, and bar-code scanners. Handhelds such
as the HP iPaq hx2750 have two expansion slots so
that you can simultaneously use a memory card and
a wireless networking card. As noted earlier, if your
PDA has an SD slot, see if it supports SDIO, a
necessary feature when using peripheral devices
rather than mere memory cards.
Handhelds endure rugged lives as they get tossed
from pocket to bag to desk. Some protection is in
order, but even pricey PDAs come with decidedly
cheap cases. If you know you're hard on your gear,
check out metal and rubber cases. For gentler folk, a
soft case is all you'll need--perhaps in leather to suit
your business attire. And don't forget the most
fragile component on your PDA: the screen.
Inexpensive plastic overlays are available to protect
it from scratches or inadvertent taps with a real pen
rather than the stylus. Want to buy a PDA handheld
computer?
Road warriors will need to have an extra battery for
their handheld, provided the handheld has user-
replaceable cells. When you miss a connecting flight
and have to call all your contacts to alert them of the
schedule change, it's no time to run out of power.
Likewise, heavy Wi-Fi users will appreciate the extra
juice. Want to buy
a PDA handheld computer?
If you don't have an extra cell or if your PDA's
batteries aren't user replaceable, then invest in a
travel charger. Most manufacturers supply wall
chargers with their devices, but some are too big to
ever leave the house. If you spend a lot of time in
your car, a car charger may be the best solution for
adding juice to your PDA.
Considering the multimedia prowess built into
handhelds, it's a shame that so many models come
with subpar earbud headphones--or none at all. The
good news is that many handhelds today come with
standard stereo jacks so that you can plug in better
'phones to really hear what your PDA can produce.
Some models, such as the Etymotic ER-6 Isolator,
are designed to passively block ambient noise so
that all you hear is the music. Still others feature
active noise cancellation, a technique that can
subdue outside sounds. Want to buy a PDA
handheld computer?
If you want to send e-mails from your PDA or take
notes during class, adding a keyboard is a good
option. There are several types to choose from: plug-
in minikeyboards to foldable models to ultracool
virtual keyboards. However, if you plan on typing out
a lot of e-mails or notes from your device, a handheld
with a built-in keyboard may be better suited to you.
