Need to know, many people have compared the new iMac 20" screen with the one on the macbook. I've seen the screen on the macbook (but not the the iMac). No TN panel I've ever seen is as bad as a Laptop screen (or the one on the macbook), but is the iMac as bad as the macbook screen? I can handle the little "brightness" diff between top and bottom, but if it's like a LAPTOP screen I would never even consider it to be a desktop PC. So you guys with 20" iMac (alum), is the screen just like a regular 250-300 dollar TN display or is it like a laptop screen ? Thanks for answers !
