I disagree. 120hz makes typing, mousing, etc. noticeably more responsive. I never stop noticing it. I never liked having to use 60hz all the time once LCDs were replacing CRTs. The original iMac didn't even let you choose 60hz to run the desktop at -- it only offered higher refresh rates in the menus. (Games could set the display to 60hz if they really wanted to.)
