And according to a huge amount of reviews on Apple.com, that display has a ton of problems. I looked at getting an external display (ultimately did not end up purchasing) and I had made up my mind that the Thunderbolt display was an absolute "DO NOT BUY" compared to just the older cinema display
Many of those reviews have to do with a lack of USB 3.0, or a lack of support with PC's. Not with 'problems' with the display.
A large number of them are individuals who bought them for their windows machines thinking they would work. Unfortunately, it doesn't. Only one Motherboard is known to support the TB display. I do think Apple should be more forward about the compatibility.
