Revealed today was Microsofts brand new Xbox Smart Glass. This is a new system which allows seamless syncing between all Microsoft devices. As demoed, it now allows users to watch new films whilst receiving useful information on portable devices (such as Windows tablet). In the demo we saw tablets being able to help control gameplay, such as by selecting tactics and runners in American football.
Smart Glass also allows users to use their phones/tablets to browse the web on Internet Explorer (coming to Xbox this fall). This is yet again helping to integrate the whole Microsoft suite and creating a flowing experience.
