The following link has some really nice screen shots of the new OS for the TabletPC. I have used this myself and love the recognition improvements and the TIP.
Great TabletPC blog and posting all of the latest from COMDEX 2003. http://www.kstati.com/default.aspx
See me at Autodesk University 2003 with my Tablets all running AutoCAD 2004. I will also be doing a small presentation with Microsoft at Autodesk University on the TabletPC. One of the devices I will have at AU is the Panasonic Toughbook 18. This Toughbook is exactly what its name implies and is a magnesium housed TabletPC. You can drop or throw this device with no ill effects. It is completly waterproof and even read the screen in full sun.
