Live Anywhere announced at E3

I think the possibilities behind the new service announced by Microsoft (by Bill gates himself) at the Games show E3 today is quite incredible.

Start a game on your Xbox, continue it on your mobile or your Vista PC. What you transport is based on your gamertag!

Even better you will be able to play on your Xbox against opponents on Xbox Live using a PC! I have some friend playing hard on Battlefield PC, I can imagine the fun to share some action with them from my favourite gaming console.
Maybe I can dream, but I would like to imagine something between the Xbox 360 and the PS3 players.
