"Mysterious company" censors unflattering Steve Jobs video
 

Steve Jobs: Ultimately it comes down to taste. It comes down to trying to expose yourself to the best things that humans have done and then try to bring those things in to what you're doing. I mean Picasso had a saying, he said good artists copy, great artists steal. And we have always been shameless about stealing great ideas and I think part of what made the Macintosh great was that the people working on it were musicians and poets and artists and zoologists and historians who also happened to be the best computer scientists in the world

well, a lot of the greatest things are stolen


the idea of a GUI, stolen by Bill and Steve from Xerox

the AK47, stolen by Kalashnikov mainly from the M1 Garand and the German StGW 44

90% of Vista, stolen by Bill from Steve

If by stolen you mean seeing how it can be improved upon, then maybe.

If MS wanted to directly copy OS X they could have done a much better job of it, really. Perhaps having an understanding of Vista's inner workings will help you. http://arstechnica.com/reviews/os/pretty-vista.ars/1
