There are a few USB ports, but I have no idea what you would use them for since you can't play music/videos off of them. I guess for storing games and other game related data
.
Yeah that's what I was thinking too. I think they tried to pull the same thing with the 360 but they caught enough backlash that they added the capability in a dashboard update. Hopefully that's what's gonna happen with the One.
Also there's no backwards compatibility with X1/360 games? I haven't tried any of them yet but that kinda sucks too. I could see no X1 compatibility but if I ever wanna pop in an old game I gotta use my 360 :\.
