MacBook Air 2012 11.6", 13", or MacBook Pro 2011 13"?

I've currently got a MacBook Pro 13" (early 2011 model) with 2.3 Ghz, i5, 64GB SSD, and 8GB RAM. I've been wanting (in my head I've been needing) the new MacBook Air. I can sell my Pro for around $800 and just dish in the rest of the cash for the Air, but I just don't know if I should.

I use applications like Screenflow, Final Cut Pro X, Motion 5, and Reflection maybe about once per week in order to edit a video for my YouTube channel. I don't do any heavy after effects or anything, just some editing for my channel. Would anybody happen to have the new Air? If so, does anybody know how it performs doing those simple tasks? It'd help me out a lot! If you happen to live in Florida, my MacBook Pro is up for sale! Lol

Any comments would be greatly appreciated (unless they're negative).
