I have to admit, it takes a bit of imagination. Of course it only came in one color and one body style, but it got you where you wanted to go. Then a competitor offered a new car with a sleeker shape and a different color and Ford had to offer some choices. If that hadn't happened, we might still be driving black Model T's today. Oh, they'd have better radios and radial tires, but a Ford would no-doubt be stuck in that same paradigm.
Competition drives innovation and improves customer choices.
This is business fact. Destroying all competition is a disservice to the consumer. The problem is not the quality of the Microsoft OS known as Windows it is good enough to do what most of us need it to do. The problem is that we should be using much more powerful and robust operating systems and developing new applications that run in them. Look at the world of console gaming and you can see how consumers win from competition.
