Years ago, I had a tv about the size of a remote, with the tiniest screen imaginable. I bought it so I could watch my shows without having to go inside in nice weather. I didn’t have a vcr at the time.
Unfortunately, the batteries ran down much too fast, and I had to keep replacing them. So THAT turned out to be a waste of money, rather than an investment.
Of course, there are all kinds of devices for watching tv now.
