Give Peter's info, does ClearType look better than Standard on all of your monitors? Or are you just saying that anti-aliased fonts look better than aliased fonts?

The reason I ask is that my personal experience is that ClearType looks bad. I've not used XP's implementation, but I've used it somewhere (I want to say MacOS X, but I'm not sure of that) on a laptop LCD screen and had to turn it off almost immediately because it looked so bad -- and I tried different color ordering and everything. It just looked rainbow-y whereas the normal antialiasing looked fine and grey.
