Watching YouTube and I ran into some material about these mini-computers that just plug into a TV and you have a full-size computer. The memory on some can be up to 2Tb. It was shown that the little case about a 4×5 or even smaller, could be hooked up to many different other units and would never get hot or slow down. I went to Amazon and looked at some, but a decision has not come yet.
Just for information and to sidetrack some boredom. I hope to feel better soon, two days now.
