The 13" Macbook Air has a 1440x900, the new Macbook Pro has a 1200x800 screen. The Air has a discrete NVIDIA GeForce 320M video card, the Pro has an integrated Intel card. Besides the CPU, why would I buy the Pro over the Air?

The 320M is usually considered an IGP and it's roughly the same performance as the Sandy Bridge IGP.

I think you underestimate the 1 GHz CPU difference. Also RAM slots.
