did you find held up better to daily wear and tear? Obviously, the MBP is sturdier and less delicate than the MBA, but perhaps the lightness of the MBA helped it avoid banging into things that in the end it held up better than the MBP? What's your experience? Did you find yourself less likely to drop the MBA, and if you did drop it, did it sustain less damage because it's light and thus hit the floor with less force?? Or is there more damage with the MBA when dropped, but also less likely to be dropped because it's light? Thanks for any insight!
