which laptop at $1000 can rotate its touchscreen by 90 degrees? only one i can think of right now is the msi slider

Asus Transformer.

Runs Android, not a full OS with access to the kind of stuff the surface has access to. He's talking about $1000 laptops running a full-featured OS.

Asus Transformer running Ubuntu? :) Admittedly, you cannot get that off the shelf...
