A Consumer Intelligence Research Partners study analyzing smartphone platform loyalty surveys found that 81 percent of existing iPhone users purchased another iPhone during the 12 month period surveyed. Meanwhile, 68 percent of existing Android smartphone users bought another Android device. During the period, nearly three times as many Android users switched to iPhone as iPhone users switched to Android. In other words, iPhone users appear more loyal, and more apt to upgrade to the latest device available on their platform. [Source: AllThingsD]
