I am not a Bionic owner bit I am no stranger to rooting. I, along with lots of people, love the control that rooting gives you over what is or isn't on your phone. You can make it look nearly any way you want, run backup apps that work, and use your phone to it's digital potential.
It is a little scary the first time through the process but after that it is a breeze. After having a rooted Droid X forever and know the GNex...I don't know if I could go long without it. Take the plunge, join the dark side, and have some fun.
Oh, and my favorite part...basically flipping the bird to Verizon...don't forget once rooted to flip them the bird or else your phone fails and the world ends.
