PDAs are not yet hand-held PCs, but have been used by many people over
the years. PDAs are better-known as pocket pc's or palmtop organizers.
PDAs have many uses including: mathematics, use as a timekeeper with
calendar subroutines, browsing cyberspace, sending and receiving
e-mail, video, typewriting and word processing, name and address book
functions, making and compiling spreadsheets, reading bar codes,
receiving radio broadcasts or stereo listening, playing computer games,
entering poll results, and GPS. More modern PDAs also have color
screens, MP3 music and telephony capabilities, allowing them to be
employed as cellphones (smartphones), web browsers, and portable media
players. Several now also include cameras that can photograph scenes
which can then be uploaded to Flickr and mySpace accounts. Virtually
all newer PDAs can surf the Net, intranets or extranets via Wi-Fi, or
Wireless Wide-Area Networks just about all PDA's utilize touch screen
displays leaving out Smartphones which depend upon menu systems
attributable to their tinier display screens.
PDA's Past
The term "personal data assistant" was first used on Jan 7th, 1992 by
then Apple Computer Chief Executive Officer John Sculley at the
Consumer Electronics Show (CES) in Las Vegas, Nevada, concerning the
Apple Newton.
PDAs are occasionally denoted as "Palms", "Palm Pilots" or "Palm
Tops" so-named after an early personal digital assistant produced by
USR and Palm Inc called the "Palm Pilot". Today however, the term is
much more encompassing and includes a very diverse range of products
developed by a host of many manufacturers including HP, Dell,
Blackberry and Sharp to name a few.
.Characteristic capabilities
Presently, a regular PDA has a touch screen for data entry, a
memory card slot for data storage and at the least one of the following
for device-todevice communication: IrDA, Bluetooth and/or WiFi. All the
same, many PDAs (normally those used primarily as cellular phones) may
not have a touch screen, alternatively using softkeys, a directional
pad and either the numerical computer keyboard or a thumb keyboard for
idata nput.
In order to meet the PDA definition, standard software should
include an appointment calendar, a task list, an address book for
business and personal contacts and some kind of notes program. Internet
connected PDAs also usually include E-mail and Web support.Most units
also include memo recording software for audio notes. Very handy for
remembering important details.
Not Quite A Laptop Replacement...Yet
Possibly, to a higher degree than any other computer device, the
personal digital assistant lacks the raw computing horsepower and
Wireless Broadband capabilities of a desktop or notebook computer.
Presently, costs of laptop computers are coming down. Although a good
deal bigger in size, laptop computers have more full-size screens and
keyboards and are have greater computing power.
However, the OQO Model 2 has been brought out in recent times as a
fully desktop PC compatible PDA with a USB port so that people can use
their normal work and business software or play computer games
compatible with ubiquitous operating systems such as Windows XP. It can
also connect to regular PC peripherals. Costs still have a way to fall
prior to mass adoption takes place in the market but OQO is no longer
the exclusive manufacturer of these types of units, so costs should
fall possibly within the next few years.
Conclusion
The PDAs strength is that it is easy to transport and less bulky
than full-sized computers.It slides easily into a dress shirt or
trousers pocket. The additional features like cameras, Global
Positioning System, telephony and MP3 player make it flexible unlike
any other type of computers in the market.
A lot of people simply don't need full desktop features while
actively on the go. As long as they can access their information and
sync their data to a full-sized computer when they arrive at their
homes and offices, that's really all they need and want to do. So at
least in the short run, the PDA will most likely remain as a portable
helper for millions of users for years to come.
