I used to go along this line of thinking, and had a "dumb" TV for a long time. I would spend hundreds of hours trying to get a PC/xbmc/kodi setup with a remote control to be comfortable, but always required a keyboard and mouse next to the TV. In the end it was a waste of time and I wasn't enjoying my TV as an entertainment device.
When I finish work, I want to sit down and just have everything work. I don't want to have to keep getting up and pressing buttons and messing around to get a myriad of supplemental devices of varying quality to work. I just want one single device, on the wall, with a remote.
