I suppose the MacBook won't get much, if any slimmer in future revisions since in doing so it would encroach and take away from the MBA's largest differential; it's thickness. Kind of bummed, but not too much to care. Was assuming they would do a slightly slimmer redesign when they switch out for LED's on the MB. Any slimmer and the argument against the MBA becomes "no DVD/CD, less HD, etc for $800 more and only slightly skinnier?" for the majority of consumers looking at MB & MBA.
