On Channel9 the Cleartype team posted a 16 minute movie about the new longhorn fonts and Cleartype itself…
“What is the one thing looked at more than anything else on your computer?
You never think of them, right? Well, that’s by design: good fonts aren’t noticed for the most part but they are important in how usable your computer is and how easy it is to use for a long period of time and how productive you’ll be on it.
The Cleartype team, which makes both fonts as well as the technology to display them better on your screen, were hanging out in the hall the other day so we turned on our camera and started talking.”
