just bought a refurb machine about 3 days ago and got a pretty awsome deal $800, never used with 46 weeks of warrenty remaining! originally i was going to get a macbook unibody, but after i found this deal i couldnt resist..even though iv heard many bad things regarding the rev A air's. Im comming from a dell xps m1300 t9300 2.5ghz 4gb ram 13" led 8400m 500gb and 6 + 9 cell battery. The machine is setup to dual boot with OSX and Windows 7. About 6 months ago i would of never even considered a macbook, but as time went on i started using windows less and less until i caved lol. I have to say after using the air for about 2 days im fairly impressed. its uber thin, light, easy to transport, loving the big trackpad, multitouch, the quality of the machine and the screen, while it is a bit slow compared to the t9300 osx runs just fine and so does windows 7 on bootcamp. I gotta say, im officially converted! Im not sure if ill keep the air or sell it for a unibody as iv already had it overheat on me once. one thing i am wondering though is if i have too many problems with it will the apple store replace it with a new rev A if my problems persist after they keep repairing it? also what you guys recommend in the ways of cases/protection?
