Curious about some of the details in why Google switched to their new Roboto type face in Ice Cream Sandwich? Matias Duarte, Android director, took to Google+ this evening to explain it in great detail. Switching from Droid type face to Roboto type face was mainly due in part to the higher pixel density screens, Matias explained. As screens get bigger, and more pixel dense, certain font schemes can lose their luster.

The other big part of the new type face was also due in part to the design strides Google is trying to make with Ice Cream Sandwich. You’ll notice in screenshots that fonts are much more crisp and tie in better with the rest of the UI.

The Android team is devoting themselves to continue working on the font, and the overall UI. We can’t wait to check it when we get our hands on the Nexus Prime in a few weeks.
