rely on our browser more stable and fault-tolerant as possible. If a single page or plugin crashes, the rest of the browser should not be affected.

Slide 12: …and then give it away?
• Android is no way tied to Google services
− You could use it to build a Yahoo or Baidu phone*
• We’ve open sourced the entire platform
− Hosted at kernel.org, not Google servers − Will grow the core technical team to include many other
entities
• People don’t need a partnership with Google to launch
Android-powered devices
* I leave out Microsoft because they would probably use Windows Mobile.
