hello Guys, I have the MBP in my signature. i want to sell it and buy the new air. how is the i5 of the air compare to the 2.4ghz core2 duo? I know that i'm going to love portability. my only concern is the graphics, i use external screen for viewing hd videos. i don't play games on the mac. Do you think is worthy upgrade? to be honest my current mbp serves me well, apart from the fact that i don't like to take with me most of the times.I can sell it for £800 to £850. I never been fan of the air before, but know it looks really interesting.
