Apple 27-inch iMacs having performance issues

It's not at all clear what the root cause of the problem is, but we've noticed a big uptick in people complaining about performance issues on new 27-inch iMacs on Apple's support boards. The most common symptom seems to be incredibly slow Flash video playback, but people are also claiming that there's a bug forcing the hard drive to spin down, that there's a corrupted Snow Leopard build preinstalled, and even that the problem is bad permissions, which is basically how an OS X user gives up trying to figure things out.
Apple hasn't said anything yet, but neither of the 27-inchers we have here are having problems, so we're keeping our fingers crossed while we wait for an official resolution. Video of the issue after the break.
It seems like every time Apple releases a "new" product, there's always something wrong. Graphics issues. Hard drive issues, all your Information deleted issues, etc - and now this. It seems they are rushing out products and skimping on quality control - which is driving away customers and damaging the reputation of a company which charges a significant premium for "quality".
the past when you had very little software available for the Mac, but now that they are growing there are more and more problems like this popping up.
If you have an isolated situation where this happens, then you can notch it up to a defective unit, a user who did something to cause it to happen, etc. But when you have this type of thing happening over and over, Apple is not doing their job in testing this stuff. People like to critize MS for rushing the 360 to market before doing the work to make sure it does not overheat, but this here, is the same, it seems as if Apple is worried too much about rusing their products to market to appear like they are innovative, ahead of the curve, but they are only going to harm themselves and the customers.
If you are having problems like this, there can be multiple causes - a driver that does not function as well at the higher resolution, a bit of OSX that has a bottle neck with special hardware built in. Luckily, those types of problems can be fixed with software. But they need to make sure it works first. We have heard of MS' compatibility testing labs where they test various software combinations for perf and compatibility. I, personally, have been to a MS developer lab where they bring in customers to test their applications before Windows shipps. Windows is available to developers and general users months before. But except for a few betas put out and accessible by a select few, Apple does not do any real compatibility. And in the end, it is going to bite them.
