It's not too surprising that Steve Jobs and his methods have been discussed pretty extensively over the last few months. While reading one such article (viewable here), I came across a nice quote from a supposed exec who has previously worked for both Apple and Microsoft:
Microsoft tries to find pockets of unrealized revenue and then figures out what to make. Apple is just the opposite: It thinks of great products, then sells them. Prototypes and demos always come before spreadsheets.
The origin of the quote is really irrelevant; if more companies picked up this mantra, the world would surely be a much more awesome place.
