I remember in the Masters Tournament a few years ago when Mickelson won it all, he birdied the final hole to win.
His approach shot on 18 landed in almost the exact same spot as his playing partner's. The guy he was playing with gamely took his putt first, allowing Phil to see how the putt would roll (which direction it would take, how hard to hit it, etc).
After having seen this guy try almost the exact same shot, and miss, Phil was able to learn from his partner's mistakes, and hole his putt.
My point is that there's something to be said for watching someone else make the initial blunders and capitalize with a better product. There are plenty of market share leaders that weren't first to market, but perhaps came slightly afterwards...
