ok, 128GB of storage is not enough for me. 256GB would be nice, although this would not be my primary computer but since they are (about to?) make 256GB SSDs that can fit into an Air, I'm willing to wait. A few issues however, how long does Apple usually keep its models? I don't care about speed bumps or other minor changes, but I would hate to be stuck with an old looking MacBook Air. Since the Air was originally released around Q1 2008, how long would they normally keep it before refreshing it? I realize according to the site, it still has 2 months average before seeing an update, but how soon after they update it would they change it completely? Thanks!
