Well I'm not going to paint Apple as being rosy and perfect, either, but I have not seen this "yellow screen" issue, nor have I seen the image retention issue, on mine or any of the ones I've seen in the Apple Store (granted, there's not much time to try the IR test on the store display models).
The one I bought looks great to me. We'll see if that changes in the future, but for now, it's fine.
