My ultimate favorite feature of the MacBook Air? - The LED screen. It's so gorgeous and it's so bright that I only really use full brightness in direct sunlight - this screen is so gorgeous it trumps any cons about the battery life. (Also love the fact that the LED screen is exclusive to MBA and optional only in 17in MBP - as well as keeping multitouch functions only for MBA and MBP - good marketing strategies and instills good equity and pride within early investors of MBA.) Also, a close second.. the keyboard and the way it is designed is amazing. As each day goes on, I feel more confident in the decision I have made to purchase this laptop.
