I think Windows itself was ripped off from somewhere. Internet Explorer was purchased, and they renamed it. They also discourage growth in new innovations. When a company announces they are going to develop a type of software, Microsoft soon after, announces they are going to work on the same thing. Immediately the smaller company stops development because they can't compete with MS, then MS simply sits on the project.
Window was ripped off from Apple. Dos was ripped off from Seattle Computers in the 80's and Internet Explorer was ripped off from Netscape. Bill Gates said himself in the book he wrote, "The Road Ahead" the internet is insignificant. He is a farce, the only thing Bill Gates is good at is contracts in his favor and stealing software. We had a computer business in Seattle 1983-1994 and I know many programmers that threw in the towel on writing software. They figured what's the point, Bill Gates will just steal it.
Well, we always have BitTorrent when new versions of Office are released for $600.
I wouldn't ever do such a thing though......../smiles
