I personally find it much more comfortable and relaxing to be able to hold a controller in my lap while looking up at a TV. With games on my phone or tablet, I either have to strain my arms holding it up high enough to be in front of my face, or I have to strain my neck to look far enough down that I can hold the device in my lap to play; there just isn't a comfortable way to play a mobile game for more than 5 or 10 minutes.
