It's an app. They are programming it to work with Windows 8 and Xbox. Sony is making a PlayStation app in contrast, but they also have the Vita on top of that.
I'm not sure what the limitation to these apps are. So far I haven't seen much but secondary screen menus and control inputs from either, but if Gaikai expands it could allow for back catalog gameplay on smartphones and tablets. Not sure what MS is going to do with smartglass though, they haven't really talked much about its future. Not that I've heard.
Before the PS3 everyone was nice to me :(
