Android tablets are great, but they never quite seem to hit the heights set by the Apple iPad — neither in terms of build quality, weight, responsiveness, nor general versatility. In an attempt to change this, Google has released the Pixel C tablet (along with a choice of expensive keyboard covers), which it hopes will paint the Android tablet experience in a whole new light. But are they successful in this, or is the whole idea just academic in a world with affordable Windows 10 tablets and Chromebooks?
