Working with PDAs

Sometimes a laptop computer is still too large to easily work with. It’s often more trouble than it’s worth to boot your laptop to jot a note or check your schedule— which is why people still carry pocket planners and tiny notebooks.

The same improvements that have eliminated many of the differences between laptops and desktop computer systems have given birth to a whole new tool— pocket-sized computers known as PDAs (Personal Digital Assistants). These are small, memory-based computers that fit in a purse or shirt packet and provide a set of applications such as a personal calendar, to-do list, notepad, and often a small sketching application. PDAs are designed to replace pocket planners and paper notepads by making it easy to enter, access, and modify data. Many PDAs support limited forms of handwriting or printed character recognition because they’re simply too small to provide a keyboard.
