I'm excited to see what this Microsoft "Smart Glass" is. Rumor is you will be able to stream game content to your phone/tablet. Example maybe your playing Halo on your 360 and on your tablet it will show the map your playing on in real time, kinda like a more interactive radar. I'm sure however it's implemented it will be better than that example.
If your wanting to watch the press conference live here is the link to do so, I know I'll be watching.
