im selling my mini to my mom, her compaq box is over 4 years old. And im going to upgrade to a intel 17in imac. Are there any disadvanteges about getting a refurb from teh apple store? i dont mind a few little scratches for the couple hundred off. I heard the aiports are a problem but does 10.4.6 fix it? but anyway will a refurb act just like a new imac?
