8. iPhone (2007)
Everybody knew that after the success of the iPod, the only thing left to do was go mobile for absolute domination. The concept of the iPhone started nearly three years before it officially went on sale in 2007, and has released a new software update every year since. There aren’t too many things that the iPhone doesn’t do, and if you think of any, there’s probably an app for that. With the iPhone 6 expected to drop sometime later this year, the reign of the iPhone is sure to continue for a long time coming.
