How could we really describe this new impressive device ?, can we describe it as a light weight tablet or a nice light weight laptop ?. just we can describe the Xperia Z4 Tablet as the actual successor to last year’s Xperia Z2 Tablet, and very little has changed in the way it looks and feels. This is still one of the best-engineered electronic devices on the market, feeling featherweight and durable at the same time. That’s is an important and powerful combination, as it allows you to toss the tablet around like a literal notebook, not having to worry about the added fragility of it being a piece of high-tech equipment.
We weren't particularly satisfied with the low 224ppi of the predecessor, rather thin even by last year's standards and we're happy to note that the tablet's display resolution has been brought up to date and is now 2,560 x 1,600 pixels.
The Xperia Z4 Tablet is a hugely promising premium offering on the full-size tablet market. Perhaps a touch too premium. It is the only mainstream tablet out there to boast IP68 certification and manages to do it in a super-slim and lightweight body. And that's one of the major question marks hanging above it - will battery life be good enough, or has the push for compactness meant a sacrifice in autonomy?
The Z4 Tablet has evolved to now also include a capless USB port, removing the annoying flappy cover of its predecessor. The Z4 has 6,000mAh battery like the Xperia Z2 Tablet, but I’m having to recharge the newer device more often, whether I use it or not. That’s somewhat unusual for tablets, which can last for multiple days when left idling. But most importantly, an IP68 certification means you can submerge it in water for up to 30min and 1.5m in depth, without fearing for its life.
Sony augments the gaming appeal of the Z4 Tablet with the inclusion of PS4 Remote Play. Connect a DualShock controller to the tablet via Bluetooth, boot up your PlayStation 4, and stream the games directly to your Z4 Tablet.
Sony's design language has remained unchanged for a while, and while it may be getting a bit tired, it's stylish light 393g weight. A few excess millimetres have been trimmed off the footprint, while thickness has been brought down to match the Apple iPad Air 2 at 6.1mm. its 10% lighter than both the predecessor and the Cupertino rival.
The BKB50 Bluetooth Keyboard is literally just that: a keyboard. There are no additional ports or extra battery for the tablet, which just slots into a receptacle at the top of the dock and wireless connection. Once the two are tethered up, you are presented with a small task bar and something akin to a Windows Start menu at the bottom left of the screen.
