I prefer not to root. As I hate the fact that if I decide to put it back I can't fully restore it back to the way it was before I rooted. I have been reading that once you root you can install the stock rom but phone is still rooted. So if you have a problem and bring the phone into the store your warranty is voided.
Its easy to return it back to stock. Don't let some sort of misconception scare you from rooting it and thinking you can't. You can.
