Many times a " refurb " / " used " unit was sent back because the purchaser was not bright enough to use it. A few days ago I was at my eye doctor sitting in the waiting room and an elderly lady ( probably in her 80's ) asked me if that was a tablet. I said yes and she said she had one but couldn't figure out how to use it. She had an Acer she said. Unfortunately she didn't have it with her so I couldn't help her. She was stumped trying to get online to her bank. Said she had the user id and password but couldn't make it work. I didn't get to ask her much because they called me in. I don't know if she bought it or one of her kids gave it to her ( likely ). But some people just should not have these things or even smartphones because they aren't able to use them. It would be interesting to know the return rate where people buy / get one given to them and just can't handle them.
