I like the trackpab idea- borrowed from ipods. Could be useful for photos. I would however like to see it on a MBP for me to buy into this latest development.
MBP already have the capability for this IMO, since the trackpads support multi-fingered scrolling and double-tap Must be a software thing. Might appear in the next version of the OS.
I'm not all that enthused about the Air. It's just too small and inflexible - yes, it's small and portable, but that's not really what I need. I just prefer my 17" MBP
