My reason was because the iPhone really proved revolutionary to me in the space of then touchscreen phones. I upgraded from a Sony Ericsson K770i to an 8GB iPhone, before upgrading in 2008 to a black 16GB iPhone 3G. So far, only 1 hairline crack around the headphone jack but it's quite hard to see, so I ignore it. I decided to skip the iPhone 3GS as it was not really worth an upgrade (to me personally) with the same design and the much complained build quality problems. Back to the point, the iPhone to me was eye-catching, had a brilliant OS and served all my basic needs as a student, sometimes even making me leave my MBP behind while just attending lectures with a small but overwhelming device. What was the reason you got an iPhone?
