I just got back from lunch where I checked out the MBA at the King of Prussia, PA Apple store. It is pretty nice but it definately feels like it could break easily. I did want to warn people that go to check out demo units though. The machine seemed rather snappy. So after a quick check, all 3 demo units that the store had out were solid state drives! I went over to an MBP and the application load times were significantly longer. I would just make sure you know what you're demoing so you're not disappointed when you get the HDD model a realize how much slower apps fire up. I have decided not to buy a MBA because you can't upgrade the RAM. However before my decision, I wasn't even considering the SSD model. However now that I actually used it and experie3nced how fast the load times were, if I was buying one I would get the SSD model.
