Sony Xperia Z Ultra
If there's one thing Sony is known best for, it's making gorgeous displays, and at 6.4-inches the Sony Xperia Z Ultra ($TBA) has the largest and slimmest full HD display of any smartphone. In case your phones always seem to find their way into a body of water (or a beverage), it's also waterproof — so there's no need to junk it up with a bulky case. This Android smartphone comes with a 2.2 GHz quad-core processor, and 4GLTE, so it's ready to handle just about any gaming, professional, or video application.
