My Air has recently been plagued by the heat issues spiking up to 75C at times and then having a core shutdown independent of the heat at times. I went to the 5th avenue apple store and asked a store employee what I should do and he was like wow you should schedule a genius appointment and we'll get you a replacement, well i couldnt stay in NYC so I came home and went to the king of prussia store upon speaking with a genius he told me its a known issue and i have to wait for a software update....soo my question is whats with that? ive followed these boards and seen how many people have gotten replacements with a smile, the guy wasnt rude nor brushed me off it was just a bit disheartening to make it sound like i should just deal with these slow downs
