Make Text on Your Laptop Easier to Read

Microsoft offers a free online service that claims to improve font display quality over traditional forms of font smoothing or anti-aliasing.
ClearType improves readability on color LCD displays with a digital interface, such as those in laptops and high-quality flat panel displays.

The online tuner lets you tune your Windows XP ClearType settings.
