I've been trying it out as a monitor; I'm not sure it's really usable as such; text looks pretty bad on it. I'm hoping that fixing that just requires some calibration. There's a detailed discussion of this display here: http://www.reduser.net/forum/showthread.php?98027-1299-Seiki...
In any case, it definitely seems 2013 is the year we'll start to get affordable 8MP monitors, which is great news for those of us running 2-3 30" panels.
Delicious 4k in 32", I can't wait.
Plus bonus link of Crysis 3 on said monitor.
