I've always discounted the "big boy" HTC class devices as being too large, but recently I was looking around for something larger than a phone, but smaller than a full sized notebook. The HTC Advantage looks pretty good. Have to test the browser though. Might be better off with a UMPC class device.

Needs to run tangler though.
