According to French website FrAndroid, prices for the Xperia Z4 Tablet will start at €559 in France - this is how much the Wi-Fi-only version of the slate will cost. The Xperia Z4 Tablet with LTE should cost €659. If you want to buy the new Sony slate together with a Bluetooth keyboard (which transforms the tablet into a mini laptop), you'll have to pay €659 for the Wi-Fi-only model, and €759 for the LTE one.
Measuring 254 x 167 x 6.1 mm and weighing 389 grams, the Xperia Z4 Tablet is the world's thinnest and lightest 10-inch slate (it's just as thin as Apple's 9.7-inch iPad Air 2). But that's obviously not the only highlight of the Z4 Tablet. Running Android 5.0 Lollipop, the device sports a 10.1-inch "Live Colour LED TRILUMINOS" display with 1600 x 2560 pixels, and is powered by an octa-core Qualcomm Snapdragon 810 processor. Other features include an 8.1 MP rear camera, 3 GB of RAM, microSD card support (up to 128 GB), and a 6000 mAh battery. Moreover, just like Sony's previous tablets, the Z4 is dust- and water-resistant (IP68-certified).
