not even had it 2 weeks yet and the left cmd key has broken. i don't have a clue how it happened. i've been babying my new air. i freaked out when i saw it's first scratch (thanks to my cat). came home on saturday and noticed that the left cmd key wasn't pressing down. upon further inspection i saw a small piece of plastic stuck. managed to remove it with the help of a needle. didn't remove the cap in the process. the key works fine but obviously something has broken underneath and now the key is loose. i'm not happy that this has happened to a computer i bought only 2 weeks ago. if it had happened in a year or two from now then sure, fine, **** happens. i'm not going to even attempt to remove the key cap incase it breaks any further and i'm not paying for a new cap/scissor mechanism. i just paid £1079 for this machine. i've booked an appointment with the genius bar tomorrow. will they do anything? if it comes to it then i will just need to buy a replacement cap/scissor mechanism. how easy is it to replace it? thanks!!
