Vote for the Most Important Gadget of the YearS

Every year, thousands of new gadgets emerge out of busy factories dotted along the eastern edge of the world: shrink-wrapped, matte or glossy, plastic armies marching to line the shelves of Best Buy and the warehouse floors of Amazon.

A hundred or so are worth talking about. A dozen or so we'll remember in a few year's time. A couple really matter. But only one is the most important gadget of the year. And it's up to you to pick it.

Here's how it works: You vote for the most excellent gadget in each bracket, and the winner moves on to the next round. Wash, rinse, repeat each day this week until we crown a champion, NCAA playoff-style. And just like March Madness, the gadgets are seeded (roughly) by where we expect them to fall—but the real fun's in the upsets.
