One of the sexier smartphones to show up at CES 2013 is Sony’s new Xperia Z. The flagship handset features a 5-inch screen, 1080p display, quad-core processing, and 13-megapixel camera, all wrapped up in a slick, hyper-flat chassis with a glass backing. Taking decent photos and video in low light should be easier with the camera’s HDR mode. So yeah, odds are this phone will induce its share of drooling. Good thing Sony’s engineers thought ahead and made it water-resistant.
