I may be looking for a handheld PC for home use. Im not really looking for anything fancy, just something to wirelessly surf the net on while away from home (or check out wifi hotspots with it)
UMPCs are the most fully featured (and expensive). They run Windows XP with a 7" touchscreen.
If you want a PDA sized device, as well as all the pocketpc versions, look at the Nokia 770. It's limited in other areas, but designed purely as a hand held web browser.
