I purchased this a few months ago and it’s already gone dead. Took it to the Apple store and they could not revive it and said it would cost over $400 to fix. I came back to the seller and they basically told me that the 90 day warranty is passed so basically I can go pound sand. So, they have the legal right to deny me satisfaction, but from an ethical or good-faith-business perspective… Just hope you don’t get a lemon! I am living proof that lemons exist within these MacBook Airs.
