Apologies if this has already been posted. I know all the current excitement is on the Macbook Air, but watching the demonstration with the new trackpad features (such as wipe, rotate, and all that) makes me wonder: couldn't these features be implemented onto current Macbooks and Macbook Pros with a software update? Unless there's some large difference in trackpad technology between the three machines, I don't see why not: my MBP can recognize three fingers on a trackpad. I know this because two-finger scrolling cuts off when a third finger is placed on the pad, so obviously it can tell that many digits. I know I wouldn't mind some extra functionality on my MBP. Do you guys think Apple will keep this a MBA feature just as a selling point? Or do you think we'll get multi-touch in the future?
