We are talking about a 3.1 lb MBP versus a 2.8 lb MBA with basically the same dimensions. In addition, the Air has a dimmer screen, fewer ports, inferior display color space, and from what I've read, inferior thermal headroom. The two things the MBA has going for itself is better price and price to performance ratio. It also has a longer battery, but the gap is thinner than it once was (11 hours vs 10 hours).
