Sony has announced an 11-inch, 0.39-inch thick tablet with keyboard cover. Does the design sound familiar?

The Acer P3 ‘Ultrabook’ uses a similar design running the Core Y-series CPUs. The ASUS Vivobook Smart does a similar trick with the Clovertrail CPUs but the one most people will be thinking about is the MS Surface Pro which runs U-series Core CPUs. In many respects, the Tap 11 trumps them all by offering Haswell, the next generation Intel processor, in a very thin design.  The question is, what’s the battery life like?
