So I purchased my MBA in late April...this was after returning (2) 2011 MBP's in the weeks prior due to malfunctions in both....Now my MBA is acting up, Kernal error's, overheating with the fans whining when I'm on the internet on non-flash based sites, slow wake-up (sometimes the cursor is frozen for 5 seconds, sometimes the screen won't turn on for 5-10seconds), beachballs when just opening safari or typing in a url...I don't do anything intensive on it either, just surfing, and watching media on vlc. I can't believe I've had this kind of luck on my 3rd mac in less then 5 months... I would love to go to the apple store and have someone look at it, hopefully exchange it (I see that as the only reasonable thing to do given my situations in the past), however I am in a remote location for work and won't be home for 3 weeks. By the time I come home the new MBA 2011's should be out. Is an exchange now out of the question because of this forthcomming update? What should I do I need suggestions. First time mac-purchaser.
