In our house, we have a 1st-gen ATV, Roku HD (again, older gen), and an XBox 360. We've largely found them redundant in most senses, except for the following:<p>Can't watch Xfinity on the Roku or ATV, can't watch Netflix or unfiltered Youtube on ATV (can't get any VEVO content on the ATV), can't rent Amazon movies (prime is OK on 360) on 360 or ATV, and can't serve music from multiple computers to 360 or Roku.<p>We can flip that around and say that no one device gives us all of the entertainment (and gaming options) that work best for us. I like to play a few games here and there, so there should be some console. I haven't even bothered to bring in the cable box (it actually only got plugged in long enough to authorize us for XFinity) because I've run out of HDMI ports (there's a blue-ray player in there too, because I'm sure as heck not going to pay Hulu for their buggy service just so we can stream the Criterion Movies, when most are on DVD/BD)...<p>I like the concepts that MSFT is showing off here. I haven't reviewed the remote music service from MSFT in a while, but last time it lacked the simplicity of the ATV, especially for multiple libraries. If they've got that improved, the ATV is gone. (Having no other real value to us.) If they'd remove the restriction from paying to rent videos on Amazon, the Roku would be gone too. My partner uses all of these devices for her entertainment, and would happily switch to just an Xbox 1 if it does the job well. I'd be happy to have to maintain fewer devices (each with their own problems, let's not get down that path!).<p>I'm not sure about the source of much of the angst here, but it does sound just about exactly what our household has been looking for.
