So far - so good with the new iMac I bought today. I may have the ever so slightest yellow tinge on the bottom - but I honestly think I am seeing things b/c of waiting so long for the issue to be resolved. Gonna let it run a few days and post pics of the screen for folks to critique. This is quite the upgrade from a single core Celeron 2.4 Ghz with 512 MB of RAM (6 years old!).
