I had a Microsoft Surface and freaking loved it. It was part kindle, part tablet, part laptop, and part full PC.
At home I used it as a kindle for books and a tablet, and in the event I went to a meeting it worked as a laptop with it's little keyboard. At home I also had it hooked up to two monitors and used it as a work station from time to time.
This is my Sufrace at a meeting with the little keyboard...
Any my work station at home...
When traveling to a show or any location where I would be for a few days, I brought a portable monitor... I think it's 19 inches, super flat, and fits in my carry on. With a portable keyboard it's like having a full PC with you on the road.
This is my set up in Vegas one year at the Hard Rock Hotel during Internext...
