The SIII is one helluva smartphone. the nature UX is indeed very nice and soothing, with many features like smart stay, s beam, and so on to bring this phone above the android crowd. However, after a while, the UI simply gets boring, I love the phone for one thing, the raw power that it possess. After rooting and installing custom themes and so forth, I've fallen in love with the phone again, and it's absolutely amazing at everything I put it through. If you are one to invest time to root and customize your phone, this phone is definitely worth it. If not, sticking with vanilla android from the nexus series would be a consideration.
