I've been vacillating a bit on ClearType recently. I love ClearType in theory. A threefold improvement in horizontal resolution on LCDs is an incredible step forward for computer displays. Internet Explorer 7 forces the issue a bit by always defaulting to ClearType for web content, even if you haven't enabled ClearType in Windows XP.
