Debating whether or not to buy a brand new or refurb imac. Does anyone know if you can get your student discount when buying a refurb imac? And what is the discount? Read other threads about the discounts on imacs & kinda confused. Is there a difference on the discount on a brand new one vs a refurb? Oh another question...which one is better the alum or white? Are the really problems with the wireless in the alum ones?
