Just bought a 21" refurb iMac, and so far I have to say I'm delighted.... except I have found a single dead pixel. I'm still well within the 14 days, so I'm considering swapping for a new machine. What have previous returners done from here? It's a refurb so do I have to buy a whole new machine, or will they replace it if I report the dead pixel? I have read the article that says I need 8 or so dead pixels to get it replaced by Apple, but that seemed to be about brand new machines in warranty after the 14 days. I'm happy to return it straight away, although as it's the holiday season I likely couldn't source a replacement until next year, and I'd like to get a hold of one. It would be a shame to return it only to be unable to purchase a similar machine. What would you do good people of Macrumors!?
