I get what you're saying. If someone gave me a Ferrari or a Lamborghini to drive, I would crash in seconds. I cannot handle so much power. That's why I drive a Honda. So simple that even I can figure it out.
If I wrote to Ferrari and said "All I do is drive back and forth to the movies now and then. Can't you build a simpler car for people like me?" they would say "Friend, you need a Honda, not a Ferrari."
What you want is the Honda of computers, and they have been around for ages. Here are a few ideas:
The Telikin is a computer built specifically for seniors, and so is the GrandPad. These are great computers and you'll never have to worry about all that crazy technical stuff. A Chromebook is another great solution, and not at all expensive. A Chromebook is basically a browser and email machine. They are real easy to use, because Google (who created the Chromebook) manages all the complicated stuff for you. A Chromebook is what I use most of the time.
But if you're planning to stick with a Lamborghini, well, you can't expect them to make it into a Honda.
