Surprisingly, big name handset-makers, like Motorola (NYSE: MOT) and Nokia (NYSE: NOK), didnt even make the list. For comparison, Google (NSDQ: GOOG) ranks 68th and Amazon.com (NSDQ: AMZN) ranks 52nd. To have a handset-maker like RIM top the list of companies—which spans a bunch of industries—provides a new sense of perspective in an industry, where hype can certainly overshadow reality.

Clearly, the BlackBerry is making a graceful transition from the business world to being a serious contender in the consumer market. But whether it will be able to keep up the growth, especially with increased competition is the question. As the fastest-growing company, Fortune says RIM has a three-year average earnings per share growth of 84 percent and revenue growth at 77 percent. The company’s stock has a three-year annualized return of 45 percent (and that’s including the economic meltdown). That’s pretty hard to maintain.
