I'd pay 400 dollars just for MacBook's lovely, lovely multitouch glass trackpad (I'm not kidding). I can't imagine my life without it (I'm not saying envy your was a bad machine or anything; just saying MacBooks offer more than just OS X).

The Envy line has a giant multi-touch trackpad as well. It's not glass, but it's a nice smooth plastic, and it's huge.
