I have an ARM 400 mhz processor in my IPAQ 2210. Superb build quality & lots of free software
Tech support when I needed them - very very good.
A very versatile machine runs TOMTOM 5 no probs (GPS) lots of aftermarket accessories for it.
Video & MP3 playback fantastic, runds pocket word and excel quickly.
A great machine .....
HP iPAQ rx3715 looks even better than mine !
