You'll need to spend another $120 if you want to get the special keyboard cover for the Surface Pro.
The Surface Pro is a souped-up version of the Surface RT tablet that launched in October. It's a bit thicker and heavier, but it's powered by an Intel chip and capable of running older Windows apps.
Think of the Surface Pro as a traditional laptop crammed into a tablet form factor.
The Surface Pro will be available at the Microsoft Store, Microsoft's website, Best Buy, and Staples.
