I went back and forth between a MBA 13" and a MBP 17". There are stark contrasts here. So why did I end up with a MBA 13"? It has the form factor akin to the iPad; in that you can take it anywhere. When you're carrying a MBP or other larger notebook around you sometimes feel like you might be carrying too much with you. The higher resolution on the MBA convinced me overall. Since I've had the MBA, I guestimated that I'd use "Remote Disc" at least a few times. I've never used it and never needed to. Software on a disc is almost always older than what I can download online, I don't play games or music - but if I did it would be digital/App Store anyhow. A 15" Air would be a great addition.
