I've been debating whether the portability of the 11" was worth the screen size or not. Well, I just realized how incredibly portable it is. I was about to leave for to get some work done and went to get my macbook air. Then I realized I had no idea where it was, since it wasn't on my desk. So I checked my backpack, the only place it could have been. And sure enough, it was in there. The catch? I just did a ~25mi bike ride last night, with the backpack on. Completely unaware I was carrying a computer the entire time She's a keeper!
