I used the iPhone for over three years but now I'm hooked on my nexus 4 and Google services. Stock android is so nice and I would say is just as smooth as my iPhone 5. Once I got used to how android works and really explored all the good apps it was a no brainer to switch. Of course, I still have my iPhone 5 just to see what Apple does software wise this year. I don't expect much of anything but just in case they do drastically just iOS I will have a device to test it.
