I got one in the beginning of July. No problems at all, I think the screen is great. I am very fussy about screens and I was very worried about getting one with issues. I was going to wait for the next gen but then I realized that I needed the light for summer time (family vacations, sitting on the poorly-lit balcony at night). I love it and I'm glad I didn't wait! I haven't seen one with the color issues but I do believe I would notice that. At past jobs I have been notorious for complaining about my monitor until I got a better one.
Also I scored nearly perfect on that quiz where you line up the blocks in order of hue. So there are my qualifications.
