These are certainly valid reasons. My iPhone 5 just gave me 8.5 hours of strenuous usage. In that, I played Super Hexagon (exclusive), played music and watched YouTube through AirPlay, browsed the web with a fantastic mobile browser, and chatted with iMessage. All in a beautiful, super thin and light phone. The camera is best-in-class, the chip is best in class, and the ecosystem is bar none. Is it that hard to see why people like iPhones?
