Sony has launched the SmartWatch 2, an update of its Android-based watch, while the competition still seems largely to be in development mode. The company is also hoping to attract users that want a smartphone with a really big screen with the 6.4-inch Xperia Z Ultra. Smart watches have been in the spotlight recently, with reports that Apple, Google and Samsung are all working on products. But Sony is already offering a third-generation device in this category with the SmartWatch 2, the company said on Tuesday at the Mobile Asia Expo in Shanghai.
