Thank you for the reality-check. I really do appreciate it and hope anyone reading my words reads yours as counterpoint.
I had tried to be fair-handed with my judgment of the Seiki but I admit that my desire for large form-factor displays coupled with Seiki delivering one that I can actually afford clouds my judgment some. I want high-quality large displays and the incumbent manufacturers have left me in the cold for a decade.
Not that it matters, but one area where I spoil myself is in monitors. I spend what I can afford (and then some, admittedly) on monitors in lieu of other luxuries. I own five 30" monitors, three of which are Dell U3011s. I love those monitors. As you point out, they ship from the factory with great color, a matte screen, and of course inputs that don't disappoint.
But on the flip-side, the 30" "professional" LCD monitor as exemplified by the Dell U3011 and U3014 has not decreased in price substantially since I picked up my first Dell 3007WFP, what was it, eight years ago?
Maybe it's telling that I have not yet replaced one of my home Dell monitors with a Seiki. But when my wife's Dell 30" died, we decided to give the Seiki a try. As I've said, the Seiki has several downsides. The 30Hz lag is foremost. It's noticeable and frustrating. But the screen size and delight of having so many pixels in a single display is so compelling. Also, after applying the Seiki firmware update, the backlight can be adjusted, allowing for better calibration.
It's not a perfect monitor. It's not even a great monitor. It's a good monitor and it does the thing I value most: give me pixels with which to see and interact with information quickly. As a programmer on a budget, it's my favorite monitor currently available. I really hope that competition heats up and better monitors are on the horizon. I will bite at opportunities to get large, high-DPI, high-quality, high-speed displays.
But for now, I personally would not buy the Dell 30" unless they severely cut the price. I'm keeping my eye on that because I am hopeful the new competition could start moving the higher-end prices downward, and that will make me happy.
(Incidentally, the U3014 is presently $1,600 at Newegg [1]. I could barely stomach the ~$1,000 price of 30-inch monitors eight years ago. In 2014, I can't bring myself to spend $1,600 for 2560x1600.)
