-Gates announces a new platform called Live Anywhere that will roll out when Vista ships. It will be a big part of Vista. It will have cross-platform capability. Mobile phones, Xbox 360, and PC will share tools.
A demo of this new platform is given. Whenever you log onto a system you\'ll log onto Xbox Live. An interface is shown on a PC that uses the same "blade" system as Xbox Live. No matter which platform you are on you\'ll sign in with the same gamertag with the same friends list.
Marketplace will be available on all systems. Now you can download content like Zuma onto your mobile phone. As an example Major Nelson mails a custom car from his phone to a PC. Then begins to customize it on the PC and throws it into the game.
