This is Asus's Fonepad. Not to be confused with the Padfone. It's a 7-inch tablet priced at £179...which also makes calls.
The 7-inch tablet runs on Jelly Bean and has a 1280 by 800 pixel display, and is the same size and same resolution as Google's Nexus 7 tablet. It also doesn't have a back facing camera, because Asus understands that taking pictures with a tablet is not okay. But it does have a 1.2-megapixel lens on the front for video calling.
The tablet runs on a Qualcomm Snapdragon chipset, and has 64GB of storage. Apparently tablet phones are a thing now, so we might as well just accept it. Sigh.
