I don ' t know , most people say Prius drivers on this sub . <| sep |> There was a point in history where grown men didn ' t brag about being weak and light objects as somehow being a burden to carry around . I have a mid 2010 and it has issues but weight is not one of them . The text books I had to carry around in middle school and high school when I was a teenager 9602 were far heavier . When I walk home from the grocery store with bags in each hand , that is way heavier . The kettlebell I use every day weigh 70 pounds . 4 . 7 pounds is seriously no big deal compared to most other things I have had to carry around . If that is some burden for you as a grown man you should sort of be ashamed to admit that unless you have some disease which greatly affects your strength . I would rather keep the weight , keep the size , and throw in more power . Keep the air models as the light weight versions for people who lack adult strength . I would rather have a dedicated graphics cards that will blown away competing computers sold at less than half the price . A $ 4300 Macbook pro should not suck at anything . It should be a class leader at whatever you throw at it .
