AnandTech has another extensive LCD article and while portions of it 
dwell on image quality other portions go into some detail on lag and 
response time of panels (and they test 8 or so of them) so anyone 
thinking of using LCD displays would do well to read the article:

                                                /"\

                                                 X

Trying to be happy is like trying to build a machine for which the only
specification is that it should run noiselessly.
