While the public is just getting "Cupcake", at Google I/O, Romain Guy provided a first look at three big developments in Google's open source mobile OS which will be part of the Andriod 2.0 update, codenamed "Donut."

-The first feature was "Android Search," a universal search tool that allows contact information, applications, songs, and more in-phone content to be located in addition to content on the Web.
-The second, acts as a complement to the Voice Recognition capabilities, and adds Text-to-Speech (TTS) capabilities to Android. The API will come with the new open source text to speech engine (Ice Vox?), and will ship with voice packs for different languages.
-The final feature is a gesture upgrade that recognizes handwriting.
