The best pocketPc is NO pocketPc.
Toshiba's e740 range SUCKS...
The WiFi model has bad reception and with WiFI on all you'll get is an hours use.
If you really NEED a pocketpc get an ipaq 5400.
Skip ALL the cheap brands like viewsonic etc... as accessories for them are rare.
You might consider the Dell models if you need cheap but for the best in the market the ipaq is the way to go.
P.S. Why not the P800???
