From a ZD Net article a couple of days ago.

I might wait.
The Surface Pro is a pretty perfect device for me, and honestly is what I have been waiting for in getting a "Tablet" for myself. I would LOVE to pick one up on release date.
But, it seems like it is launching at a bad time. With Haswell right around the corner, and the fact that Microsoft has already hinted to a Surface Pro 2 (plus, you know other device makers will make similar form factor devices this year), I think I may end up waiting for the next iteration or a more powerful device made from a different manufacturer later in the year.
It's such an expensive device, I'd at least like it to be somewhat powerful for a few years - but it looks like it's going to be outclassed pretty sharply by devices launching this year.
