The Sony is the better option for sure. With the battery slice you have 8+ hours of actually use time. The slow mechanism allows for touch screen in bth tablet and laptop mode. And though some criticize the small keyboard of the Sony duo I think it is actually great piece of design work as it keeps your fingers closer to the screen making it a more natural and fluid motion when typing to tapping/swiping the touchscreen. And have you seen the screen on the duo? Brightness and contrast is best I have sen yet on an ultrabook
Revolutionary. One device designed for all jobs. Browsing, presentations, typing, mobility and working with a partner. The simple idea of installing a dual-TFT on the front and rear is to revolutionize using a Windows PC.
