pros to rooting; longer battery life, much faster, the ability to customize almost everything, currently im running bamf's complete port of sense 3.0 which is AWESOME!!
cons to rooting; the chance of bricking your phone permanently, rendering it as useful as, well, a brick. and rooting will void your warranty so if you run into a problem with the hardware and want to get a replacement you must unroot it, but if the situation ends up bricking it and you cant unroot your kinda out of luck and may have to pay full price for a replacement.
