Recently I read one of these predictive articles that industry pundits love to make. Usually they are the kind of article you can reread in five years and have a good laugh. The headline read iPad casts shadow on MacBook and of course I got sucked into reading it. The article took the point of view of walking into an Apple Store, talking to some of the employees, and getting the impression that the MacBook Air, and in fact maybe the whole MacBook line was doomed.
