Have you considered the sony vaio Z? You can get a 1080p screen, 2 SSDs in a raid 0 or 1 configuration, a DVD/Blu-Ray player (think you can put another HD here instead), core i7 processor, decent battery life (6/7 hours), standard amounts of RAM, 13" and 3 pounds. It will blow your air out of the water while being the same weight and size. It's about 0.5" thicker although.

I do iphone development, so I'm stuck with what apple has to offer, but if I didn't that would be my machine of choice.
