I personally think weight matters, but not thinness. I used to use a 12" Powerbook. I now use a 11" Macbook Air. I still use the same bag to carry it around. Being thinner didn't win me anything. However, being lighter is a definite win. Hypothetically, if I could get the same laptop that is thicker, but cheaper, but is the same weight and has full sized ports for things like ethernet (or ports that were removed like SD cards, firewire, etc) instead of requiring dongles and attachments, I would get the thicker one. (A coworker bought a 15" Powerbook the same time I got my 12". We went to a conference and were lugging our laptops all day for a week. The weight difference took its toll on my coworker by the end of the week.)
