I never thought I'd ever buy a MBA. At the time, I couldn't bear to lose the ports (Ethernet, FireWire) and the SuperDrive. It was also too expensive compared to the 13" MBP. I was really drawn to the 11" MBA because of how small yet powerful it is. Storage space was also a problem/expensive. But with the 2012 MBAs, I think Apple has finally brought the future and made it affordable. School starts soon and I need to buy a new computer. I thought of the MBP vs. MBA and which one better suited me. This time, I went with the MBA because of these reasons: 1. I have not used the SuperDrive in my previous MBP in over half a year. 2. I have never used the FireWire port. I've had a 13" and 15" MBP before this MBA. The last time I recall using a FireWire port was to import video from my Dad's Sony HandyCam cassette-based camcorder using my iBook G4. 3. I only used Ethernet when I was in a temp apartment this summer that didn't have a wireless router set up yet. So in reality, much of the bulk that I have been lugging around on my back is for nothing. On the plus side, the 13" has a higher resolution screen, which is one of the things I missed going from my 15" to 13" MBP. I love my new MBA! The thing is incredibly light, the SSD is super fast and I'm really happy with this purchase. I just wanted to share my thoughts in case anyone else is thinking about getting the MBP or MBA.
