The display always lags the iMac update. Surely they will finally upgrade this product once 5k iMac demand dies down. They've waited so long and now every component of the TBD is outdated- the case, every port, screen matting, and screen resolution. Since so many won't be able to take advantage of 5k, I would think they would produce a standard resolution version with the newer ports along with a 5k version. They could've done the cheaper version a long time ago, but I guess it's better late than ever.
I bought a new pixel perfect WQHD PLS 27" monitor for $300 with PIP, 2 hdmi, and display port in and out after waiting years for a new TBD. The standard resolution monitor from Apple will likely be way overpriced for what it is. When they first came out they were a great deal, but with quality monitor prices tanking, there's no compelling reason to pay more than triple for the Apple product. The 5k will likely be reasonable for what it is now, but with time will become overpriced as well. I don't get mad at initial Apple prices, but when they continue to sell outdated products at the same price as when they were cutting edge really gets me. $1000 for a display that every component is outdated, some components for years?
