It's a weird world we live in. Why not at least try the voice commands?
You say this as if they're some unknown. Those of us who don't want to use them know what they are, how they work, and why we don't want them. I don't use the radio on my Xbox. Heck, I don't use the radio AT ALL. When I do stuff outside of my room and want music, I use my Lumia 920, which has over 2,400 songs--more than enough to do the dishes to. I know where my controller is at all times, so I don't need to find it.
You are making the assumption that we all want our console to serve as a single machine for controlling all media, but that's not how we all work. I use my gaming console for gaming. If I turn on my Xbox, it's to play a game. I don't turn it on to watch Netflix (which I don't use) or listen to music (do that with my phone) or to play with non-gaming applications (have my PC for that). If my Xbox is being turned on, there is a 99.99% chance I am going to play a game, with the .01% exception being when I go to start a download of a game (after which I turn my Xbox off and let the download run in the background, like with Games for Gold titles). Because of that reality, I don't need voice commands. Telling my Xbox to turn on does not serve a useful purpose over pressing a button on my controller, it just does not.
My desktop is my multi-use device, not my Xbox. You're telling us to open out minds to new possibilities, but maybe you should open your mind to the idea that we're not all looking for our consoles to do all of the stuff that you want.
