Some quotes from Steve Jobs about Microsoft:

• The only problem with Microsoft is they just have no taste. They have absolutely no taste. And I don't mean that in a small way, I mean that in a big way, in the sense that they don't think of original ideas, and they don't bring much culture into their products. --Triumph of the Nerds (1996)
• I am saddened, not by Microsoft's success — I have no problem with their success. They've earned their success, for the most part. I have a problem with the fact that they just make really third-rate products. --Triumph of the Nerds (1996)
• I wish developing great products was as easy as writing a check. If that was the case, Microsoft would have great products.
