This is what I would get.
This is worse than a Macbook Air for the OP. Worse GPU and a heavily throttled CPU, making it slower than the Air for emulation.
edit:
Love my MBA '12. When I have it in my backpack, I basically have to check if it's still there every now and then, it's so light. The battery lasts a working day and the trackpad is glorious of course. It's really a great laptop, one that's actually comfortable to use when you're in the train for instance. Due to smaller screen sizes on laptops when compared to desktop, the OS makes you a bit more productive with the mission control function as well.
I haven't really kept up, but at the time it was the best the choice for Ultrabooks. I can't really imagine other manufacturers were able to catch up, and then I mean in regards to the the touchpad mostly.
Even if they did, scrolling on Windows is so janky it wouldn't really make a difference.
