When on the road, I use a PalmOS PDA.
1MB ROM (containing Palm OS and built-in applications)
2MB RAM expansion
4.7 x 3.2 x.7 inches
5.7 ounces, including installed batteries
160 x 160 pixel reflective, pressure sensitive LCD screen
Proprietary RS-232 serial connector (readily connected to a more normal DB25/DB9 RS-232 serial connector)
If this was useful, let others know by an Affero rating
