Undeniably, Apple, with the iPhone, has revolutionized the mobile market. Apple did what all mobile device manufacturers and service providers have dreamed of and failed to do for so many years, which was to make the phone an Internet device. A decade from now, nobody will argue that Apple was the company that reinvented what a phone could be.
However, the big question is how long the iPhone will stay the leader of the category it created. Will Apple maintain its market leadership against an ever-growing number of mobile device manufacturers and a variety of well-supported, open, modern mobile platforms (i.e. Android, and maybe Windows Mobile)? Most importantly, will Apple succeed at keeping mobile developers under its control?
