I had a MBA ult rev. B that broke and now I'm thinking of buying a new MBA. But rev D hasn't got the backlit keyboard and that is really a big deal for me. For my use (office and internet, some photoshop)the MBA ult has enough performance. but for 1kg extra I get better battery, performance and firewire with the 13" Macbook Pro. Any thoughts? How about the display? Is the Pro 13" the same as MBA?
