Summary:
i've used it daily for six months and have not found one of the problems often reported in the tech forums-no overheating-no buzzing-no dead pixels-the usb ports work perfectly-outstanding for the price [and i cant stress this too much] color and contrast and response time are all that could be wished for at 600 bucks

Pros:
see above

Cons:
it takes about 20 minutes to warm up after power-up to come to full functionality and steady-state imaging
