If you are just looking for a cheap tablet then you should get the surface rt, although I strongly recommend you pair that with one of the keyboards either the touch cover or type cover.
I was never the tablet type, but that changed when microsoft was selling the surface rt with the touch cover for around $250.
If your looking for a more feature rich and more productive tablet then without a doubt you should get Surface 2.
It has more features, more battery life, faster chip, its like a beefed up Surface RT.
