Ok, mine has just arrived and I'm typing this on it now.
First impressions:
Colours fine, brightness fine and good range of adjustment, no noticeable dead pixels. Oh and it's huge. Absolutely huge.
About this flicker when it first turns on that some people have mentioned. So far as I can tell, that's the Asus Splendid thingy adjusting itself. Mine "flickered" about twice a second for maybe 10 - 20 seconds when I first turned it on and hasn't done so since. I'll test it a few times to be sure.
Right, I'm off to test this fraps video.
