JAPANESE HARDWARE MAKER Sony announced a WiFi-only version of its Xperia Z Ultra phablet on Wednesday, transforming the smartphone into a tablet.
In our hands-on review of the Sony Xperia Z Ultra, we said that the device was too large to be classed as a smartphone, and it seems Sony has started to think so too.
The firm refers to the new WiFi-only model as a tablet, which is accurate given the device's 6.4in 1920x1080 resolution touchscreen. Beyond the new model's lack of 3G and 4G support, it seems to have specifications identical to those of the first generation model that Sony announced last June.
This means that buyers will find the same quad-core 2.2GHz Qualcomm Snapdragon 800 processor, 2GB of RAM and Android 4.2 Jelly Bean mobile operating system that shipped in the original model, despite Sony having announced that over six months ago. Google's mobile operating system is skinned with Sony's custom user interface as usual, which furnishes the tablet with Sony apps such as Music Unlimited and Playstation Store.
The WiFi-only Sony Xperia Z Ultra also features 32GB of internal storage, a microSD card slot, Bluetooth 4.0 and 802.11a/b/g/n/ac WiFi connectivity and a seven hour battery life.
Sony is also keen to boast that it's the thinnest tablet on the market, measuring just 6.5mm thick.
Sony unveiled its WiFi-only Xperia Z Ultra model in Japan, so it's unclear whether it will see a UK release. Sony has yet to respond to our request for comment.
It's not the end of the world if the WiFi-only model isn't released in Blighty though, with the original Xperia Z Ultra now available for less than £300. µ
