In case you're still confused (because it is confusing): the Microsoft Surface we've been talking about lately is the Surface RT, which is basically like a tablet. The Surface Pro, though it looks pretty much like the Surface RT, has full laptop capabilities, just like any other Windows 8 computer. And Microsoft just announced today that the Surface Pro will cost $900 for the 64GB version and $1000 for the 128GB version--though neither comes with the Touch Cover keyboard, which is pretty much essential, so you can add another $120 to that price. That'll make it more expensive than a Macbook Air. [Microsoft]
