In our living room I occasionally use a Mac Mini connected to a Sony 65 XBR, but the video resolution leaves something to be desired. The keyboard is comfortable on my lap, the mouse on the arm of a chair. But I've use that mostly to set up the Roon OS that ran on the Mini. Small portable tables designed for keyboard and mouse use in a chair or sofa are available, and coupled with a high definition TV could be a good solution.
