Took my less that 2 year old MBP to genius bar because getting online was getting sketchy. Sometimes it would work, sometimes it wouldn't, sometimes it would just take a waaaay long time. Diagnosed with needing a new airport card. Fine, dropped it off expecting to pay around $200. Picked it up today and they had put in a new logic board, as well. Good news, no charge, at all. Bad news, still sketchy trying to get online. Taking it back tomorrow, but can't help but wonder why the heck they would do that?!?!
