You obviously don't know jack, PS4 or PS3 owners (neither the Xbox 360 or One owners) have to even get up to turn on their consoles. You can do that from the controller itself.I game off my desk all the time... I have my PC dual screening a monitor an a tv. Is it an inconvenience? No. Not really. No more than PS4 users having to get up and physically turn on their consoles lol. It is funny how you seem to think KBM means you cannot play from a couch... I do all the time with my controller.
You need to have your desk close to your TV in your setup. Most people have them in different rooms and you bet it's a huge inconvenience to wire them.
I see you're spouting your typical uninformed crap again. Ever heard of a lapboard? If you want to use a mouse and keyboard on the couch you can without much effort at all. And if you just want it for when you NEED to use it for navigation purposes or some other reason, you can just use one of these:
None of those options come EVEN CLOSE to the convenience of a controller. I have that Rii keyboard, fact I have two, the version you linked, and the one without a tiny ass pad, but a gyro itself.It's as if you've never seen someone with a htpc, you think they have full keyboard and mouse in the living room to watch movies? you can have "remotes" like these

so many options, don't be ignorant
I am not ignorant, I have a HTPC in my setup, and based on my experience, none of the M/KB solutions are even half as decent as using a controller or using M/KB on a desk. They're so inconvenient that I end up having to use remote desktop to start playing a movie on my HTPC. It's overall a horrible, horrendous experience. KB/M will NEVER be compatible with the living room.
PC is perfectly fine, and most likely better to use on a desk, no question. But it has no place in the living room.
