Price is going to be critical.
The keyboard is slick, but nothing we can't get on an iPad
I think overall it's a nice package...at $500 tops.
Also, this seems to be the very definition of Tim Cook's explanation of compromise when you try to merge a tablet and "PC". Not a negative, but certainly a fact.
I really would rather see MSFT do a proper mobile ecosystem between phone and tablet, and not worry so much about windows desktop integration.
