Re: So what about...
Agreed. Personally I find 60Hz fine for gaming (with v-sync to prevent any tearing) and instead prefer the extra height of a 16:10 screen - more world on the screen with less space taken up by the HUD.
As it is, although it might be possible at a push to tell the difference between 60Hz and 100-120Hz, I'd love to see anyone who could play two machines (in a blind test) and spot the difference between 120Hz and 144Hz.
