As previously reported, the Sony Xperia Tablet Z (SO-03E) went on sale in Japan today through NTT DoCoMo. We have attached some unboxing pictures of the device below. Interestingly, the DoCoMo version appears to include a dock inside the box instead a normal charger. The back of the tablet is made out of matte plastic, unlike the glass of the Xperia Z, despite this we still noticed it attracted finger marks in some pictures. It’s a remarkably thin tablet and we can’t wait for it to launch in the west.
