Mobile Demand has announced the XTablet T8600 Tabet PC. The T8600 is a Pentium 1.1 ghz, built to MIL-STD 810F, 506.5 IV: 26 repeated drops to plywood over concrete.
Here is a pretty good press release article from Mobile Demand showing a beer distributorship using the XTablet. There are some pretty good action shots.
From the Mobile Demand website:
User friendly, integrated numeric keypad
Ideally suited for sales and delivery routes
Lower total cost of ownership (TCO) than consumer grade computers
Rugged design to survive rough and extreme handling by road warriors
