Go to the bookstore and look at how many bookshelves are filled with books trying to explain how to work the devices. We don't see shelves of books on how to use television sets, telephones, refrigerators or washing machines. Why should we for computer-based applications?
I've always taken apart calculators and anything I can get my hands on when I was younger. When I was around 12 - like, 6th grade - my parents always had around Mac computers because my mom is a teacher. So I'd always be playing around with all the crazy applications and making banners and printing things out and always into graphic design.
Nothing wrong with computer as things. They can work wonders in communications and business and medicine and everything else.
More and more software would just increase the number of tasks that the computer would help solve.
There is no doubt that, since 1977 and the launch of Apple II - the first computer it produced for the mass market - many things which used to be done on paper, or on the telephone, have been done easier and faster on a screen.
Most of the people who had PCs did not have modems and could not use those PCs as communicating devices. They really were using them for spreadsheets or word processing or storing recipes or playing games or what have you.
I have an Apple computer, which I use to play Spider Solitaire and do research on the Internet.
