CES has finally opened its doors to the public, boasting a record 3,600-plus exhibitors and 2.2 million square feet of exhibition space across three distinct areas -- Tech East (at the Las Vegas Convention Centre), Tech West (covering everything from 3D printing, health products and wearables) and the new C Space at ARIA, targeted at marketers, advertisers and social media gurus. CNET's editors have hunted out all the big news (and weird tech from the back booths that you might not have expected) to give you the best possible view of the show.
