The stylus allows the user to select options from the touch screen in a manner similar to that of using a mouse. If text input is required, a user can access an on-screen keyboard and select the keys with the stylus. PDA devices are intended for users who don't require all of the power that a desktop or laptop computer has.
PDA devices are little more than electronic calendars that have the ability to send and receive e-mail and browse the Web in text mode. PDAs also contain task managers and contact lists. Palmtop devices Palmtop computers, such as the Hewlett Packard Jornada, are much more similar to traditional desktop and laptop computers.
Palmtops are intended for users who need the power of a computer but who don't want to carry around a laptop. Unfortunately, a palmtop won't fit in your shirt pocket the way most PDAs do, but it's still very small. The Jornada tips the scale at a whopping one pound.
Palmtops typically come pre-loaded with more software than PDAs do. These programs contain most of the popular features of Microsoft Office and are capable of working with Office documents.
Another difference between the software on the two devices is that the palmtop comes with a full-featured Web browser that allows you to view graphics instead of just text. From a hardware perspective, the differences are obvious. The palmtop contains a keyboard, while the PDA doesn't. You'll still use a stylus for mouse control, though. Second, the palmtop contains a high-resolution color screen.
Most PDAs use a monochrome screen, though Compaq does make a color model. Finally, there are differences in expandability. The palmtop enables you to attach a VGA monitor through the use of an expansion card. You also can use an NE compatible network card to attach to your network. Palmtops usually have more memory than PDAs, which is to be expected, given the difference in purpose of the two machines.
Both types of machines contain standard features. Sound support and touch screens are common features of PDAs and palmtops. From a connectivity standpoint, the machines are very similar. Both contain an integrated analog modem and support connections to a desktop PC via a docking cradle or wireless infrared link. And soon wait for more command prompt tricks.
