I really like my 11" MBA for its mobility. I'm bringing it out with me during times I would never want to bring my MBP. Although in the beginning I was really careful not to bump it against anything and carried it carefully in a padded bag, I realize that this behavior gets old really quickly if you're always bringing the MBA. The best thing I did for myself and enjoyment of the MBA was to just carry it around like my iPhone and iPad in that I stopped treating it like a fragile conventional laptop. I do have it in an awesome Speck plastic shell to keep it looking nice, but now I literally throw it into a regular bag or just carry it like a book and plop it down wherever I go. Am I right in thinking the MBA is pretty tough, like an iPad?
