The smartphone industry is a fast-moving, highly competitive industry. Gains in market share are created through thin marginal differences between phones that are quickly eclipsed by other companies. This summer’s 3G innovation becomes "too old, too slow" as this month’s 4G phone makes headlines. In order to successfully compete, a smart phone maker must be able to keep up with its competition and innovate to snatch small sections of market share. Research in Motion (RIM), currently the largest smartphone maker in terms of market share with over 50 million users worldwide and 12 million units shipped last quarter, managed to carve out a section of the smart phone market for itself during the early- to mid-2000s.
