Precisely. In these contexts the Xbox definitely fits the bill. The problem I see with that is it leaves out live TV watchers (so basically sports and people who want to watch event television when it happens), and it's pretty damn expensive when you can get an AppleTV to do it for 1/5th of the cost. The 360 offers disc playback, which is good, but it still doesn't cover the cost, and for those people the value added by the Kinect is pretty irrelevant. The Xbox One seems like a fantastic media device that is unfortunately hobbled (at least in the US) by the reality of how cable television is a crappy business and if you're in a certain market segment you really can't escape having it (which means one more box, etc.)
Also, the fact that the One doesn't seem to do much in regards to timeshifting is really weird.
Yeah, I will likely always have cable for NFL, and maybe a few shows on networks that dont support the media streaming services that well, but you're right, the necessity of a cable box and the costs that come with it, definitely skews the system.
Kinda how you said, my younger sibling is taking the 360 back home to college, so I just set up a plan to hook my mom up with an AppleTV, it has MLB, its 100 bucks, easy to use, Much better deal.
The Xbox one will serve as a great entertainment hub for gamers, you still game the way you would, plus all the things
like the guy said on pastebin,
~if you care even a little about anything else, get an Xbox~
thank god for MLB.TV (greatest app of the forevers)
