Apple's temperature problems: iMac again

This is very disappointing. The 1st generation flat panel iMacs had very serious heat problems, but Apple did come up with a passable redesign. The Intel switch was supposed to make this a thing of the past.

It appears that Apple forgot that lesson rather quickly:

AppleInsider | Freezing iMacs may be victims of hardware, not software

...This and other reports provide increasing support for beliefs that the lockups and related symptoms are caused by excessive heat inside the all-in-one chassis.

In some instances, the visual artifacts become increasingly likely as time goes on....

Once again, proof that you never want to buy the first generation of any Apple hardware or software product - no matter how glowing the reviews. Apple does not have a "culture of quality" -- so customers need to wait for early adopters to do basic quality control.
