Any experience using handheld external displays to enter/display data in the field for an embedded device? Whats easist to get up and running? RS-232 or USB communication ok, wireless less ok. I suppose options off the top of head are PDA's, palm computers, smart cell phones, gameboys, or maybe they sell custom display/keyboard/communication link only units for this purpose?

RS-232C or the more robust RS422 are commonly used. You can also use a minimum IrDA stack with only the IrLAP protocol if your embedded device has scarce resources. RS-232C is certainly the easiest if your handheld device has such a port.
