With the enormous amount of 27" iMacs being returned due to the yellow tint, I wouldnt take a chance on a refurbished model. Apple is not throwing these screens away. When they replace them in other 27" models, they inspect them and if theyre within some arbitrary tolerance, theyre going to stick them into a refurb.
Youre better off waiting until this (if ever) gets fixed, before buying new or refurbed.
Make sure you contact an Apple CSR and explain your concerns to them so they log it. Ifthey get enough complaints, thye may actually do something about the defective screens.
Apple or any large corporation that sells refurbs do not put defective parts or suspected defective parts from one computer and put them into another one. Never will never did. No corporation does that. It cost them allot to refurbish a product and they don't want them coming back a second time, let alone it doesn't bode well for their reputation.
This is why they are throughly tested before they are shipped out. A new 27 Imac is not as throughly tested. Some are not tested at all as they have batches that come off the line and they test one or two a batch. Thats it. If they tested them as throughly as a refurb we would not have a "yellowing screen issue' at all. None period.
No they are not throwing the screens away, they are going back to the supplier for repair or reconditioning and to be tested not into another imac.
If a imac is returned and the screen is faulty, a new screen goes into that computer, the same screen that goes into a new one. The model of screen is newer on my dads computer than my computer and we both have 27's. I checked his serial number and it was refurbished in week 7 of this year. His screen model number is the same as several I have at the office that were replaced last week, and they were week 7's as well. His screen is perfect.
A refurb is more likely to have less problems and you save money. It's a win win situation. A refurb will end up with a newer replaced part than a new one. There are allot of imacs 27's that have been manufactured in weeks 50 through the first of the year that I know I would not want, they most likely will have issues since it is before Apple even acknowledged a 'yellowing issue' at all. They will have 'older' screens than a recently refurbished 27 being sold at the Apple store. And you know most of those refurbs got returned because of the screen issues, most likely. Now that isn't to say that the new screens being put in a refurb are perfect and do not have issues, even though it is a new screen not all screens are perfect.
So a refurb is most cases will have newer replaced part, another reason to buy a refurb. A refurb being sold now has the newest screens available, if you buy a new one it may not.
The base 27 for 1449.00 is the best deal on a imac in the Apple store or any other store for that matter.
