I really don't understand the appeal of the Air. Macbook Pros are only slightly more expensive and will see a refresh soon. As a grown adult male, the extra 2 lbs of weight does not bother me.
I also carry a lot of stuff in my bag, including a camera, a/c adaptor, and a some other computer equipment. 2 lbs doesn't seem like much but if I have to be mobile for a long period of time, it's definitely noticeable.
Would I get it? Probably not. I don't have that much expendable income to have a power laptop and a luxury netbook.
