We're all frustrated at the wait for Ice Cream Sandwich on our phones and tablets, but maybe a little Roboto on your computer can help fill that void. The Android design team has popped out some official Roboto fonts that can be installed on just about any device that can display True Type fonts, and they look great on your desktop or laptop. Getting them is easy, just download them from the Android Design page, and install according to your OS specifications.
They'll give you a fresh, clean look that's easy to read and scales great. The best part is that they're absolutely free for use and "without restriction" for use in applications, so developers can use them in things like Web apps and desktop widgets. Sure beats the Comic Sans look. See the source link for downloads and the specimen book.
