After considerable reading, I'm thinking of buying the refurbished 24" Alu iMac from Apple online. I've read that maybe the refurbished models are better than new ones because they go through extra quality scrutiny. But do you think the refurbished models would likely be the ones returned to apple because of the gradient display problems? And if Apple does *not* think it's a problem, I'm afraid that they won't do anything to fix it but try to pass it off to an unsuspecting customer. Has anyone bought a refurbished Alu Imac 24", and how was the display? My PC died so I thought it's time I make the jump to a Mac. I thought this was a slam dunk but the imac display issue is making me think this out much more than I like. Thanks.
