OK Tablet Experts...

Its 8.1 windows

The Surface 2 is Windows RT. The Surface Pro 2 is Windows 8.1.

But the Pro 2 is heavy, thick, and lacking quality apps. It's a poor tablet, and an okay Ultrabook, but the screen is too small. The Pro 3 has a much nicer screen, but again, it's more of a notebook than a tablet.

What he said

Surface 2 is also the same - heavy, thick, tiring to hold and not a lot of good apps. Microsoft Store is full of junk.
