Displays from Dell that rival this in quality are not even $100 less, and don't have the docking powers that a Thunderbolt display offers. I've got a bound pair of cables (power+thunderbolt) that plug into my laptop and all of the sudden my backup drives, both monitors, ethernet and USB hub are connected. The Dell 27" higher-than-1080p monitor is nice, but it can't do all of that sadly.
