At the Google I/O Developer Conference, Google showed off some of the new HTML 5 features that it will be building into future releases of Chrome and Android 2.0, codenamed Donut.

HTML 5 offers a way to free developers from writing applications for specific operating systems by letting them write for open browser standards instead. Nearly half a billion people now use open source browsers.

Other features include support for geolocation services and a new way of adding applications to web pages.
