You want big? The 6.4-inch Xperia Z Ultra comes dangerously close to tablet territory. Sony's monster phablet struts some impressive hardware, most notably the sharp 1920 x 1080-pixel (342 ppi) display. A mere 6.5 millimeters thick, it's amazingly thin for a big phone. (By comparison, the iPhone 5s, a device regarded for its svelteness, is a relative fatty at 7.6 mm.) The Xperia Z Ultra is waterproof up to 1.5 meters (just under 5 feet) and dust resistant, Sony says. The device ships Oct. 14, but it's unclear when it will make it to U.S. wireless carriers. Some retailers are already taking pre-orders, though. Prices start at $700.
