It's hard to believe it's been a decade since everything changed. Everything
Until January 9, 2007 "smartphones" were clunky pieces of plastic junk with unwieldy styluses, hardware keyboards and operating systems that were both slow and prone to constant crashing. They were also filled with carrier branded crapware and the idea of apps didn't exist. Web browsing? Anyone not old enough to remember can never understand what it was like trying to look at non-optimized web pages on a postage stamp sized screen. Email? POP access with manual sync. Wifi? Unheard of. Multi-touch? No one had even bothered to try.
The iPhone was the culmination of everything Steve Jobs worked for. It's hard to imagine our lives without it. Even people on Android have to give respect to the 1st iPhone. It made everything since possible.
People complain that Apple is no longer "revolutionary". There were 23 years between the introduction of the Mac and the iPhone. Both changed the history of personal computing. The Mac introduced the GUI that continues to be the basis for every computer made since. The iPhone shaped the mobile age.
What will be next? No one knows, but I'm sure somewhere in a hidden lab in Cupertino they're hard at work figuring it out.
