It's all very confusing in tablet land: one minute Apple's making ten-inch tablets while Google settles for sevens, and the next Apple's making iPad minis and Google's unveiling the Nexus 10.
With a display so good you'll be able to see ghosts, the Nexus is a serious bit of kit for a seriously good price - but is it good enough to beat the latest, greatest iPad, the iPad 4?
