I am researching a new phone, thoughts here, and am quite enjoying the concept of augmented reality
If you want to get your head so far into it that it is hard to keep a handle on reality get hold of Metatropolis - a book where several authors do their own stories based on a future world that they agree on. It is fascinating but the last story deals with AR and virtual worlds within virtual worlds – great stuff!
I listened to it on audible link this link is to the UK site as I live here and can only have an account here. I do need to mention Leo Laporte and TWIT as the podcast recommended it and got me into audible.
