One other thing to consider about the Surface Pro

64GB*, 128GB
*System software uses significant storage space. Available storage is subject to change based on system software updates and apps usage.
1 GB = 1 billion bytes. See Surface.com/storage for more details.

A lot of people are complaining that you are only getting 20-30 gigs free on the 64 GB version. (Os and other apps take up to 30 gigs) Just a heads up if you plan on getting that one.
