An editorial in the St. Louis Post Dispatch...as you will see they consulted with the real experts. The best quote:
Apple ... sued Microsoft, accusing it of stealing software to create Windows. Microsoft's Bill Gates' retort to Apple's Steve Jobs has become a classic: "Steve, just because you broke into Xerox's house before I did and took the TV doesn't mean I can't go in later and take the stereo."
My view of Apple-Samsung summarized pretty well
in the Financial Times. Just bear in mind that companies that build great products generally find that more profitable to compete in the market rather than in court.
