*I mean't broke today* 2011 13.3" MacBook Air 1.8Ghz, i7 4Gb Ram /256ssd So I bought that yesterday, downgrading from my 15" MacBook Pro. I was amazed by how fast it boots and handling data's. It was working all nice and well last night, downloaded my apps etc. And then............... this morning it was dead when I opened the lid, it wouldn't turn on at all. And started to smell something burning inside it. So I took it to the Apple store, they took it onboard for repairs. My Uni dissertation work wasn't backed up :'(. What could've caused it, I don't understand!
