The newer & cheaper IPS panels seem to employ the E-IPS technology that is a modification of the older H-IPS panels. The expensive IPS panels (i.e., Apple displays--both iMac & Cinema--and some other high-end brands) are usually either S-IPS or H-IPS. The E-IPS is cheaper, but it's hard to find out why. The best explaination I found was
at this blog post, but I don't know how accurate it is.
I just bought a Dell 2209WA 22" E-IPS display for $199 and it's amazing how much improved it is over the typical LCD displays (that use TN panels). I calibrated it yesterday with my Spyder2 and while there was some difference following calibration, it wasn't substantial. I'm very pleased so far, but I haven't used it for long. At that price, though, it's head and shoulders above similarly priced & spec'd competition. Highly recommended.
