- Handheld systems include personal digital assistants (PDAs), such as Palm and Pocket-PCs, and cellular telephones, many of which use special-purpose embedded OSs.
- Hand-held systems must also deal with limited resources although their screens have recently become more substantial. Because of their size, most handheld devices have a small amount of memory, slow processors, and small
display screens.
- Generally, the limitations in the functionality of PDAs are balanced by their convenience and portability.
