The two main reasons I sold it was 1:I couldn't stand the screen issue and 2: I want to get more out of Snow Leopard. I love the new Macbook. Honestly, it isn't that much heavier when I put it in my bag. I don't know why I didn't pick this up in the first place. The one thing I will miss about the Air is the stare-downs it gets in public place. It started many conversations. I love the screen of the Macbook and the 2.4 is blazing fast however I do miss the snappiness of solid state and I have to get use to this new trackpad. No heat issues, flawless condition, fans have yet to turn on (except during updates). I couldn't bare to be without the backlit keyboard after having it with the Air so that made me upgrade. I am an extremely happy customer but I will cherish my Air days forever.
