Sony Xperia Z4 Tablet review: the thin tablet that's also an Android laptop

Lighter than an iPad, waterproof and with an excellent keyboard accessory, the Xperia Z4 Tablet is Sony's best yet

Sony's Xperia Z4 Tablet is the Japanese firm's best yet, with small bezels, a bright screen and a waterproof body - but it's when you add a full keyboard that things start to get interesting.

Sony has a solid heritage in tablets with two excellent entries into the Z series before now. While they have failed to sell particularly well, they have been some of the best Android tablets available. In fact, they have only been let down by the poor amount of tablet-optimised software for Android. That app gap between Android tablets and Apple's iPad no longer exists.

Pros: Thin, light, waterproof, excellent keyboard, microSD card slot, 2K screen

Cons: Not quite as sturdy feeling as some, expensive, variable battery life, no Gorilla Glass
