The now obsolete HP 41CV calculator was in this class. It fits into a shirt pocket and is very powerful. I had purchased one and later won one at an opening raffle. I have most of the accessories, bar code reader, printer and the third party machine language ROM. I now have an HP 48GX and it has an RS-232 serial port. It is fast enough to decode the Motorola binary data coming from my Encore GPS receiver. I have not looked into the new HP 49 yet.
3COM sold off the successful Palm series that runs a proprietary operating system, used to have NASDAQ symbol PALM.
July 2004 update.
Palm has purchased Handspring (HAND) and only the Treo name survives for phones.
Palm has split into PalmSource, Inc., (PSRC) maker of the Palm OS platform software and PalmOne (PLMO) selling the combined Palm and handspring hardware lines.Palm III -OSPro - by Oregon Scientific - Palm Pilot Compatible ( $199, $249)III (2MB upgradeable),PalmV -

Handspring (stock symbol hand) has information describing their truly plug and play external hardware interface. The external component has it's own driver and software on board so no drivers need to beloaded on the handspring. When the external device is removed it leaves the handspring clean. This would make a great interface specification for normal PC operation to avoid the hassles with drivers.
I hope this will now (2004) show up in new models from PalmOne.
