What were the most exciting developments at International CES this year? It wasn’t the wafer thin TVs from Sony. Nor the curved ones from Samsung. Not even the augmented reality glasses from Osterhout Design Group rate. Each of these can be classified as simply the latest in the we-made-it-because-we-could brand of products that are seen every year at the world’s largest electronics show. They may be cool, but they’re the history of CES — not its future.
