I purchased a 24" Imac, with OSX Snow Leopard) in March, 2009. Since then, I have had persistent, frustrating problems. They include: long delays in videos loading before playing - or not even playing at all, a dark screen, a disc drive that perpetually scratches and ruins discs (it was replaced once under Apple's warranty - but the new one is nearly as bad), photos - including video thumbnails - often not appearing (only a blue and white box appearing with a question mark inside), and several other annoying flaws. Please do not blame my Internet speed (a sufficiently high 4 MB's or so) for any of these problems. The glitches occurred even when software updates were properly installed. My friends usually do not experience these problems on their (much less expensive) pc's. My questions is: will the new (December, 2012 release date) Imac's have similar problems?
