Apple's incredible success in moving iPhones could be due to one statistic. According to pollster ChangeWave, a whopping 99% of iPhone users call themselves "satisfied" or "very satisfied" with their device. In fact, those reporting "very satisfied" made up 74% of respondents.
This blows away RIM, with only 43% of users reporting they are "very satisfied" with their BlackBerry. Apple has jumped from holding 17% of smartphone market share one year ago to 30% today. The iPhone is hot on RIM's heels, as the BlackBerry has 40% of the smartphone market.
