Sergey Brin and Steve Horowitz discuss the availability of the SDK, that it will be open source in the future, and demo applications on the Android platform.

The “GPhones” shown in the demo vid come in smartphone and touch-screen varieties. They also utilize 3G data speeds which offer quicker load times and more bandwidth for mobile internet access. The browsers are built on the WebKit framework (the same one used in Safari, Symbian OS, and KDE’s Konqueror browser). The Google maps API is used heavily, including street view on the phone.

In addition to the cool Google app, they also show off a demo of Quake running on OpenGL. So I think it’s fair to say it runs doom! The SDK is releasing today, so we’ll have more info soon.
