Investment bank and asset management firm Piper Jaffray has released the results from a recent survey of over 7,700 American teens, revealing that 40 per cent of those surveyed own an iPhone (up from 34 per cent the prior spring, and 23 per cent year-on-year). More than that, 62 per cent intend to buy an iPhone as their next smartphone, while 22 per cent have their sights set on an Android device. Tablets also had a high take up in the age group, with 44 per cent of the survey group owning one (72 per cent of those were iPads).
