Sony Xperia Z4 Tablet review

Sony Xperia Z4 Tablet - Sony's answer to the Surface 3?

We loved Sony's waterproof Z2 Tablet and Z3 Tablet Compact, and now Sony has launched the new Z4 tablet. With an upgraded QHD display and octa-core processor, as well as a new Bluetooth keyboard dock that turns it into a 10-inch laptop, the Z4 looks like another winner. But can it live up to those expectations?
