Cnet: "The must-have update you'll barely notice"
Apple's iOS 6 is more of an incremental update than a game-changer, but with more than 200 features there is plenty to like here. Outside of the new Maps app, Passbook, and new Siri functions, most of the changes are small, but the total package is more than its individual parts.
The update will make your iPhone experience better, more efficient, and easier to use. Sure, some of the new features have long existed on other devices, and on some they're better, but that's not really the point. Rather, Apple again has managed to smooth out the rough edges and offer a solid experience across the board.
