Last week I got a refurbished 24" LED Cinema Display. I may be more picky than the average user, but I noticed a slight gradient in brightness from side to side (left was slightly darker/bluer). I called Apple and explained this, and they gave me a prepaid shipping label to return the unit for a full refund. I ordered another one, which I received today, and it looks great. I'm impressed that Apple didn't even haggle with me over it. I tried to return a display to Dell once and it was a nightmare.
