I have the updated Jelly Bean (Android 4.1.1) version. It's a really good phone. I'm a super heavy user and would like the battery to last longer, but comparing that I do and how I multitask, it's way better than the iPhone 4S. The camera is not the best, but works perfectly for my use. I like taking picture of paper notes and references, since I operate paperless... and for that it is very good. Display is very good and the overall design is much better in your hands than looking at photos. Since it's a Nexus phone without any stupid manufacturer or operator trash installed, for me it's the BEST phone in the market. Not spec wise, but functionality-design-use perspective.
