Well, a netbook could be called a fully functional Windows computer as well, depending on your needs really.
The Surface Pro is a bit too thick and heavy to be a nice tablet, and not quite suited for actual serious work due to its crippled ULV processor and a netbook-sized screen. Sure you can technically run Photoshop/CS on it, but who's going to drop $700 for a license and then squint at the 10" screen? Not that many people I bet.
