what do you think of the Yamakasi?
Excellent. I've have had the monitor since the end of July and there have been no problems with it. There were no dead pixels, however it is slow to warm up compared to other monitors and it lacks the bells and whistles found on most monitors. To nit-pick the on/off LED is distracting and the promised manual wasn't available. Also the power cable supplied is a strange Korean thing, but is easily swapped for a standard North American one.
I plan to get another two monitors in this taxation year and I'm currently watching the prices dropping due to another two suppliers selling this machine. Life continues to improve.
