David:
Go buy an Asus Eee Pad Transformer with the keyboard dock. It is a 10.1" tablet that transforms into a netbook. In addition to everything that I wrote earlier, I should also explain that I can use it to run Risa3D, Visual Analysis, WoodWorks, etc., using PVN to my office desktop. I could also run AutoCAD or Revit, if I wanted to. Available for purchase online for the past 2 months. The 16 mb tablet is $299. The 32 mb tablet is $399. The excellent optional keyboard dock is $149. Right now, you can only buy the WiFi-only model, but you can tether it to your 3G or 4g phone. I am typing this from a hotel conference room on the Kona Coast of the Big Island in Hawaii.

Stan Caldwell
