My mid-2007 iMac has the yellowing "issue" and it seems it still exists. What makes you think that they will all of the sudden be on top of it this year?
I am not directing any anger towards you, if that is how it sounds. I am just very upset with it. I love the iMac. Can't wait to see what they have in store for the refresh... But my screen has looked like **** within a year of purchasing it and it saddens me to know that they still have not done anything about it.
I'm sorry but building and designing a very compact great looking complete PC in the back of a 2" thin screen chassis will always give you some trouble with particles, dust and residue from the components inside the case !
This is why I dumped the iMac before I even unpacked it and shipped it right back to Apple.
Will never ever buy a computer and display in one small unit - NEVER
