The Past The Future
What is a PDA?
PDA stands for Personal DigitalAssistance
Even though many handheld devices have been introduced since the 80’s, they are not defined as PDA’s.
PDAs were first introduced by Psion in 1984, it was called the Psion 1
Apple introduced the Newton Message Pad in 1993
Palm Pilot was introduced in 1996 by U.S. Robotic and 3Com with functioning of Stylus pen.

PDAs run on several different operating systems . The two most common are Palm OS and PocketPC (Windows-CE). Most applications have been written for the Palm OS, but the PocketPC is catching up. Other operating systems include EPOC,BlackBerry, Psion, and PocketLinux.
In 1996, a product called the PalmPilot was released by US Robotics. The Palm Pilot ran on an operating system made especially for that device, called the Palm OS.
The Palm Operating System (Palm OS) is the current leader in the PDA market, accounting for 70% of the market share. The Palm Pilot (now known as just Palm), became one of the fastest growing computer platforms in history, reaching the million-sold mark faster than the IBM PC or Apple Macintosh.
Today, the Palm line has grown to include a variety of models. In addition, a number of other companies such as IBM, Qualcomm, and Symbol Technologies released their own Palm OS PDA models, with Sony's version hitting the market later this year.
Although the Windows CE Operating System is the leader among home PCs, it holds only about 10% of the PDA market.
The latest version of Windows CE is coming back with a vengeance. They have partnerships with some key companies in the industry like, Casio, HP, and Compaq, who all manufacturer PocketPC devices.
But perhaps Microsoft's biggest ace in the hole is the coming onset of broadband wireless.
Needless to say, compatibility is going to be a major issue in the coming years. And with the world already utilizing a number of Microsoft products, PocketPCs might just slide into favor simply due to ease of portability.
The third major player is EPOC, an operating system developed by London-based software developer Symbian. EPOC has three device designs: one for mobile phones, one for PDAs, and one for home PCs.
EPOC does have some major advantages. It is an extremely power-efficient operating system -- other operating systems require double to triple the size of a battery. Also, EPOC has a small memory footprint and compact code, which allows for easier customization. This potential for customization is a huge advantage over Windows CE.
Recently, Symbian announced a deal with Sony whereby the Japanese giant will use the EPOC platform and possibly a range of applications in its forthcoming line of devices, such as mobile phones. This is in addition to deals already existing with companies such as Ericsson, Motorola, and Psion.
With a good, flexible product and a support from key companies, EPOC has a lot of potential to make it in mobile market.
Regardless of the type of PDA, they all share the same major features:
Microprocessors (Main CPU and DPS)
input device - buttons in combination
with touch-screen or keyboard
desktop PC software
- TI-Enhanced ARM925 Microprocessor
- TMS320c55x DSP for Multimedia Enhancement
