Windows RT 1.0 or 2.0?

Trying to decided if I want to wait for a Windows RT (or Pro) version 2.0 or if I should grab the 1.0 version out now?

I kind of hate the idea of buying hardware thats about to be replaced, I have a generation 1 ipad and the thing is almost useless at this point. I dont want to upgrade in a year or two.

Thoughts? Opinions?
