More than a few from what I have read on Macrumors and Applesinsider , and the 21.5s also have been affected . Lots of QC problems , too , it seems , with many of their products . Dell would do in-home service in Japan on a desktop .

MacRumours is unreliable; AppleInsider is only reporting that a few 27'' units are having trouble with Flash content.

Not really. The biggest QC problem Apple's had since the Intel/x86 transition was misapplication of thermal paste on some CPUs.

Excellent. Just beware that you're buying a Dell in the first place. They are no longer the quality leader, if they ever were.
