Another in the long lone of real iPhone killers.
Doesn't matter if you have a S2, a Nexus 4, and Xperia Z, a HTC One, a LG Optimus or even a Huawei Ascend P2
They are all easilly iPhone killers, they all run the same apps (so you can switch between any of them), and they all cost less than the iPhone. (in the case of the Huawei and the Nexus, half the price of the iPhone), without losing anything, infact all being far more functional and just as easy to use.
Whilst Android has always been ahread of iOS in terms of power and flexability, Jellybean really was a game changer for Google, it's now massively ahead of Apple in the usability and look game too.
The Nexus4 totally kills the iPhone in every area, and is over half the price. Get one for you and the wife for the same price, it's a compelling offer.
Guess that's why Google just reached the 750m Android device mark. (more like 850m when you add in all the non-Google enabled Android devices).
