Apple's troubles with their 27-inch iMacs just never seem to come to an end.

In December, Apple notified its authorized resellers that new volume orders would be pushed out about two weeks, following numerous complaints about screen flickering and yellowing issues with the showcase Mac, as well as numerous complaints from customers who received broken iMacs in shipping.

Just last week, Apple finally started shipping replacement 27-inch iMacs back to their authorized resellers… but today, Apple Insider is reporting that those same machines now have an estimated three-week ship time when ordered through Apple.com.

In truth, it seems like there's a load of issues here: while the 27-inch iMac indisputably has some screen issues that need to be further investigated, mostly, it's just a victim of its own success: it was the best-selling desktop system in America last quarter.

Still, it's got to be frustrating both for prospective customers and Apple themselves that they just can't quite seem to squelch the last of their 27-inch iMac issues. Let's hope this is the last one.
