Im getting my MacBook sent back to Circuit City...it is out of apple warranty but I have a warranty from Circuit City (where I bought it)...It is old and all cracked up...when you get the box you fill out what is wrong.I am trying to think of something that will make them replace it or give me a refund...i was gonna put occasional random shutdowns. any comments welcome but i want them to be realistic... Thanks, Kgregg
