OK thanks guys, nexus it is. And yes, I still don't have lollipop on my N7 (or G3), so I'm aware that the speed of updates isn't necessarily what it's cracked up to be.
I'll be honest, the Ipad really tempts me but the $140 price difference is a consideration and I've never actually used an apple device for long. From what I have seen, I agree that they're still the leaders in the tablet realm, it's just a slightly expensive sidestep that I can't quite justify - like how I'd murder old ladies for an InWin S frame but I'm not paying $750 for one.
