FYI Dell U3011 on sell
I have a 4-year old Dell 3007 and I'm very tempted to get this one and move the old one to my studio. I highly recommend a 30" monitor for its productivity increase.
However, with Apple's 13" retina laptop having the same resolution, it's hard to think of these monitors as cutting edge any more. If it had USB 3.0 (for my Nikon D800) and more resolution, I'd spend full price on it.
Also, keep in mind, I believe you get a 1 year warranty from Newegg versus a 3 year from Dell.
