This is actually one of my biggest concerns that keeps me from moving to an Air from a MBP. With the unibody MBP design it's actually pretty easy to do things like upgrade the memory and hard drive, and not pay the ridiculous upgrade prices that Apple wants at time of purchase. With everything soldered on the Air, you lose that choice.
