If you like Word v.X's anti-aliased text (courtesy of the Office and 10.1.5 updates), then grab the freeware preference panel silk from Unsanity. Silk enables Quartz text rendering in all Carbon apps under 10.1.5. I'm currently using it in Mozilla and Internet Explorer and the results are great. Mozilla is rendering pages as nicely as Chimera.
[Editor's note: This is a very nice little program! As I understood it, applications would require an update (a la Word) to take advantage of text smoothing in 10.1.5. But Silk somehow enables smooth text in all Carbon apps without any updates to the programs. It even applies to those apps that are currently running -- I installed it while typing this article, switched apps a couple times, and returned to find Mozilla had been 'smoothed'. Silk also includes an "Exclude" pane which allows you to specify Carbon apps that you do not want it to work with.]
