Author's Note: How Smart Watches Work

The world has heaping trash piles of dead-on-arrival digital gadgets. Smart watches, at this point, have a ways to go before they establish themselves as must-have digital tools. To emerge from the long, long shadows of super-smart smartphones, smart watches will need a killer usability that no other device can match. Currently, that killer app has yet to emerge. I'm betting that we'll see a product or two in the next year that will radically shift our concept of timepieces, for the better. -- NC
