Fast tablet. It is the thinnest and lightest tablet of its class, yet there is no apple on the case. There is also no aluminum case, only plastic. A high-resolution display, a fast Snapdragon 801 and the familiar IP-certification complete the package. Our review shows why it is still not enough for the top spot.

Sony has one of the best build quality around in my opinion....This Z2 tablet has a solid and premium feel on hand...Not everything has to be metal/aluminum to be premium.
If you want to be critical, ofc everything could be better as nothing can be 100% perfect...but as far as of now This Z2 tablet quality is equivalent if not superior than that of ipads...
