Ten years ago, after announcing the iPhone 6, Tim Cook had one more thing to show the world. Cue the first-ever sizzle reel for the Apple Watch.

It's funny watching that video today, especially when you zero in on the features Apple claimed would revolutionize the smartwatch category. There was the Digital Crown -- a so-called breakthrough in input technology that would let you scroll and zoom on what was essentially a mini wrist computer. It had a Taptic Engine that would discreetly buzz when a text or notification came in. Glances were supposed to be digestible tidbits of information, a sort of status update for your apps. Also, remember Digital Touch? That weird feature where you press two fingers on the screen and send a friend an animation of your heartbeat?
