Sony Xperia Z4 4G Android tablet – gift of sound and vision

Thinner, lighter 10-incher now with bundled keyboard dock

Review Time to recap the history of Sony's Xperia tablet range to put this new model into context. In the beginning was the Xperia Tablet, the first Sony 10-inch slab. Then came the Z2 Tablet, launched just over a year ago and reviewed here. The Z3 Tablet never existed, only the clumsily named Z3 Tablet Compact, an 8-inch affair."
