Following the accidental leak by Sony they have now officially announced the Xperia Z4 which is a  slimmer, lighter and more powerful follow up to the Z2 tablet released in May and claims to be the thinnest and lightest 10in tablet at 6.1mm thick and 392g.

The tablet runs Android Lollipop software and has a high-resolution 2K screen, which is the brightest 10in 2K screen. It also has a claimed 17-hour video playback time and runs by Qualcomm’s latest 64bit octocore Snapdragon 810 processor with 3GB of RAM and 32GB of storage.

It is waterproof, using internal seals rather than small external covers to allow exposed USB and headphone sockets.

Sony are also releasing a removable Bluetooth keyboard accessory into which the tablet slots, turning it into an Android-powered laptop that includes a trackpad, “chiclet” keys which give space around each key, custom control buttons and a hinge to hold the screen at an adjustable angle.

The tablet should be available from spring 2015.
