I am in the market for a used Psion (or any other ARM-based PDA). It must have: - a serial port - a compact flash slot - 16 MB RAM - long battery life (20-40 hours on two double-A's, for example) - a decent keyboard (like the Psion) The Psion 5X fits the bill, there may be others. Does anyone have such a PDA collecting dust that they would like to sell? If so, please get in touch. m
