I suppose if you are one to consider that and other performance boosts a main feature, the MBP makes a lot more sense to purchase. I'm not saying that the Air works for all people for all reasons. It definitely shows when it's struggling with something, and this is why I have other machines to offload things to. I don't use the Air as a desktop replacement although I do about 80% of my work on it, and that might be key to this discussion. Performance trivialities are no big deal when I can easily just head home or to my office and use a cheaper-priced desktop that still blows any MBP out of the water. > I guess it depends on how you're using it - I don't really notice the weight in my backpack, and I don't walk around with my laptop otherwise. If there is one thing I really hate about being female, it's the inability to get away with walking around dressed nicely with a backpack on. But even when I do use backpacks, it's usually the case that 1.5lb and a slimmer laptop is nicer to have and I definitely notice the added weight and subsequent strain when I'm lugging around a work laptop or my 13" or 15" MBPs instead of the Air.
