In spite of the fact that Microsoft has pirated and exploited it's way to the top, they do deserve the credit for making a rather crude pile of hardware accessible to millions and millions of people. If you think Windows 7 is complicated and difficult you should have stared at the black DOS screen back in the day. It was nearly impossible to convince people that you could accomplish anything productive with a computer. Windows made it simple and opened the power of the computer to the masses. Maybe someone else would have done it... but when you go to the bank and they say... sorry we can't cash your check now, the computers are down.... you have Microsoft to thank.
