Gadget: Sony Xperia Z Ultra

OVER TROUBLED WATER. Long gone the notion that wet is dead for a smart phone, since Sony bucks it with the waterproof Xperia series.

The latest of which is Sony Xperia Z Ultra, the slimmest (weighing just 212 grams) yet the largest full HD smart phone of today. You can stretch the imagination – and creativity – by taking pictures and creating HD videos underwater. Another plus is its high quality 6.4-inch screen that will up your mobile movie experience, aside from the full audio indulgence provided by the indispensable Sony Walkman application. Complemented with the super responsive screen and handwriting recognition, this thin device definitely punches above its weight in the high rung of smart phone hierarchy.
