Mobile apps aren't an important factor in the success of a smartphone platform, Microsoft chief software architect Ray Ozzie claimed today. Interviewed at the company's Professional Developer Conference, the veteran developer tried to downplay apps as a lure and insisted that "all the apps that count" will be available on every smartphone as the time to write and port code is much shorter than on the desktop. Ozzie instead implied that it was the OS itself and its built-in features that would make the difference.
