iPhone vs Android

Cnet put together a brief history of Android, starting with T-Mobile G1 in October, 2008. Since Android is software, not a device, the graphic below, showing Android development milestones, makes more sense. Further, in a real word comparing Android and iPhone timelines is a lot more interesting than just looking at Android alone.
The reason I'm not considering Windows Mobile, Nokia, and Palm is that they belong to the old Document-Mouse-Keyboard information access interface. After iPhone, Android became the second major technology that supported the new Stream-Zoom-In/Out application paradigm.
