“Every once in a while, a revolutionary product comes along that changes everything.”— Steve Jobs.

It’s usually hyperbole when someone says a product “changes everything.” But every once in a while, one actually does. At the Macworld conference on Jan. 9, 2007, Apple CEO Steve Jobs announced that the company had reinvented the smartphone, developing a product that combined a cellphone, mobile internet, and its best-selling iPod music player — all in one device.

At the time of the announcement, the soon-to-be iconic iPhone had more than its fair share of doubters. Microsoft‘s then-CEO Steve Ballmer said: “There’s no chance that the iPhone is going to get any significant market share. No chance. It’s a $500 subsidized item.”

It wasn’t just tech executives who had their doubts. More than one tech-centric publication, including the websites Engadget and TechCrunch, ran articles predicting the iPhone would fail. We all know how that turned out.
