Does the processing really help that much though? In most of the reviews I've seen they always seem to say that the 100hz system makes movement look unnatural, so to turn it off when watching films.
Ok, so sport contains lots of fast motion, but then so do lots of films, particularly with the current fashion for shaky handheld camerawork. And if it looks unnatural for films, wouldn't sport look wrong too?
And as for gaming, wouldn't 100Hz add an extra layer of processing, contributing further to input lag? I thought most LCDs had a game mode, which basically turns as much as possible off.
Now, I accept that it probably comes down to personal taste, and no, I'm not a sports fan. Films are the main priority for me. But I just get the impression that 100Hz systems are a bit of a gimmick, trying to trick the eye into ignoring LCDs inherent weakness with motion. After all, if you were really obsessed with motion, you'd get a plasma.
Just my two pence worth, feel free to contradict

. Certainly not worth an extra £250 in my case, I reckon.
