the smartphone, when used at home, will hook up to a tv through the hdmi out. so, if you have a modern big screen tv, you’re set there. You can attach an external keyboard if you like, and use the tablet or smartphone itself as the mouse.
My TV is, I dunno, about 26 years old. It works fine. I just can't justify the cost of buying one of those big screen things, which I would never watch anyway.
my son streams our netflix account through his phone to the tv...
