I've been thinking of the Nexus for months. However, I played with one in CPW and it just looked and felt rubbish compared to the iPad mini. Think it was the bezel that put me off. The screen appeared a lot smaller than the mini.
Anyway, I thought I might regret getting a mini, so got a full size iPad instead!
I can't understand the universally positive reviews the Nexus has got - no way does it measure up to an iPad.
The reason the nexus 7 got such good reviews because no other tablet is anywhere near as good for the same price that the nexus 7 is sold at. Also apple are far too controlling with what you can and cannot download.
