Getting a Surface Pro, but undecided.

Hey guys,

I'm really interested getting a Surface Pro. I love the idea of a full fledge tablet + laptop hybrid. The thing is I'm using a MacBook Air and a Nexus 7 but I rarely use my Nexus 7 because if I'm on the move, I'll use my phone but when I want to to do my work, I'll use my laptop. I'm in a real dilemma here. Should I just make the jump or should I just keep using what I have now.
