If you get rid of all your furniture, there's really not much left. I've done the same routine as the author, and with the same two devices (MacBook Air and iPhone). If you're single, there's no reason to be confined to one place anymore. Mobile, wifi, and battery technology eliminate any need to be tethered to one location. And laptops and smartphones are so powerful now you can easily satisfy all your personal entertainment from them (music, movies, games, web browsing, etc).

Final thought: I solved the issue of having a big screen television using a projector and pair of speakers. Connect them to your laptop and just project onto a wall.
