Is Apple’s line of MacBook and MacBook Pro notebook computers due for a redesign — or at least a refresh? The MacBook Air’s relatively fresh form factor will likely remain the same for a while, but new aluminum cases for the other MacBooks in Apple’s menagerie — ones that will key off of the Air’s thinner, slightly rounded design — might be on the way. Plus, there are some rumors that the new MacBooks — likely slated for a September rollout — will sport a glass, multi-touch trackpad.
