Far more interesting than their mysterious slate, Intel have been showing off their UrbanMax concept Tablet PC. Resembling both an HP tc1100 and an HTC Shift, the concept has a sliding/folding display and full keyboard, with an optical mouse controller embedded into the spacebar. UrbanMax's 11-inch display uses N-trig's DuoSense digitizer, capable of multiple input methods: a batteryless pen and zero pressure capacitive touch, together with multitouch control.

Although this prototype of the concept was running an Core 2 Duo processor, Intel would leave actual specs up to whichever OEM/ODM picked up the design. That also leaves some flexibility in terms of the digitizer, meaning that lower-cost versions might have a basic resistive touchscreen rather than N-trig's more advanced system.
No word on any interest from manufacturers, but there are a lot of people out there - myself included - who still think very fondly of the HP tc1100 and are beginning to wonder if the UrbanMax could be a spiritual successor. GottaBeMobile shot the following video at IDF of the UrbanMax concept in action:
