Going to be honest with you.... As the accused resident Xbox fanboy..... ...I really do not care about this feature. It has no appeal to me whatsoever and if I'm in the same area, why not just play Xbox? I get it, I promote the GamePad's functionality for the Wii U as a plus, and that's different to me in the sense of a portable for worthless crap so I can turn on my TV for background noise. I just really dislike streaming games in general, and sitting down at a PC is a lot more work and lack of convenience- it seems like you have to plan out your streaming and I just... don't care for that? I'm sure someone could use it, but not me.
Well, the idea is that you can stream the Xbox to a computer in a different room... but a lot of gamers probably have their computers in the same room, hell, connected to the same TV as the Xbox.
