I nearly went for a Nexus but eventually decided against it, mainly because of low storage capabilities when not in range of wifi.
I think that I'm going to go for a 32GB Kindle Fire. I sort of feel more connected to Amazon than Google or Apple. I already have a subscription to Lovefilm & Audible, I own a Kindle with loads of books, and buy music (and most of my shopping actually!) from Amazon. It seems right for me and also good value.
I've fallen into their trap haven't I?
