The trouble with this kind of thinking is that to remain #1, you must build a better mouse trap or be prepared to find yourself in a game of catch up. Resting on your laurels will NOT cut it! NO company is to big to topple.
When things got going in the marketplace with word processors, WordPerfect was the MASSIVE leader. It had 95% market share. Microsoft came along and bought Word from a tiny little company and tried to rebuild it to a little bit better. They succeeded. WordPerfect corporation decided to delay doing a Windows version. MS came out with a new Windows version of Word. WP had to play catch-up. They came out with a half-hearted effort at a Windows release. It was buggy, unstable and caused Windows 3.0 to actually be WORSE than it was before, if you can believe that. By the time they came out with a workable Windows version, they had 25% of the marketshare, and shortly later, had to sell the company. It's been sold at least 4 more times since. The simple moral is you can't wait for the world to catch you, they build too much momentum and sweep you under the rug.
