It may be difficult to stomach, but one of the reasons these displays are $200-300 is the Dell QA (or lack thereof). Perhaps one in five is getting a pretty good sample. The rest have to decide whether to return and play the game again.
Considering the potential quality of the e-IPS panels, I would have been willing to pay 25 per cent more for better QA, but I suspect they would have needed something like 50+ per cent more. And most of us have been buying it for 30 per cent less!
It's a tough one for Dell. The vast majority of us only buy Dell for one reason: price. Then the products turn out crappy (not to mention zero innovation), Dell's brand suffers, demand falls, and they need to cut prices (and margins) again to get sales. It's a self-destructive cycle (there's a reason why Dell and Apple have had vastly different fates -- and share prices -- this decade).
