@Jim Young: Hi Jim, actually, the guy in front of me in the line for the build keynote somehow had a surface pro (along with a surface and another W8 tablet) and was showing it off to the people around him. He wasn't a Microsoft employee, but maybe was a partner or someone working on some sanctioned software for surface or something.
It looked pretty nice, the pen functionality was very smooth. I will definitely be getting one!
Off topic, but did it have a fan?
