Some years in tech turn out to be truly revolutionary, in 2007, Apple introduced the iPhone and reshaped the technology industry. Other years are more a game of catch-up, when companies focus on the difficult but important job of making entier categories of products live up to their original promise. What kind of year will 2015 be? Here's what to expect:

Apple's debut of its smartwatch within the next few months is the biggest hope yet to popularize the internet-connected time pieces. Manufacturers have long described the mini-computers worn on the wrist-or anywhere else on the body-as the future. But so far the public has been unconvinced. Apple's watch at $349, maybe the last chance to redeem the technology.
