I've found Apple very helpful in the past -1) a battery out of warranty [ so not covered by Applecare ] just not working properly was replaced without question FOC .
2) A MacBook [ the white variety ] which was a real lemon - even the techs felt it wasn't great and it was replaced again just before its warranty expired . They even agreed that I could upgrade to the MBP by paying a little bit instead of insisting it was the MB or nothing
I can't see past Apple from my experience - though I know that some have not had the same experience as me
