US consumers said they spent 12.1% of their iPhone usage time accessing the Internet, a stark contrast with 2.4% for all mobile phones on average, according to iSuppli. Furthermore, iPhone owners spent 11.9% of their usage time listening to music or other audio, compared to just 2.5% for all mobile handset users. iPhone users also spent more time e-mailing than all users on average, with owners spending 10.4% of their time on this task, as opposed to 2.8% for all mobile-phone subscribers. In spite of having only limited corporate IT support so far, the speed (via Wi-Fi) and superior ergonomics of the iPhone are compelling users to access their personal email more frequently.
