This looks intresting....
Toshiba's JournE touch multimedia tablet (updated with hands-on video!)
7" touchscreen... and hdmi so that you can connect yet another screen to it.
With wifi , running it as a client would be really nice.
The Arm cpu seems to be running win CE 6, so it should work fine with TS as we have seen other guys using IPaq with TS.
250€ isnt that bad.
