CES 2017: Winners and losers

CES is more than just a showcase of what the latest technology has to offer -- it's a cage match of competing tech trends. The gadgets and technologies we'll be using tomorrow battle it out for our money and attention, and when the dust clears some inevitably come out on top. This year's CES had a lot to say about smart homes, self-driving cars, laptops and more. There's a lot to be excited about in all those categories, but sometimes such rapid progress can leave some people behind. Anyone building a smart-home gadget couldn't wait to tout its compatibility with Alexa, Amazon's cloud-based digital assistant.
