If you want to tether then root. You also need root to allow backup programs to back up system files. Rooting just makes life easier. I never wanted to root but now I'm glad I did. If you're happy however with what you have as most regular users are and don't care for what I mentioned then just stick with it. And you can ask this question on every other site and 90% of the time they will tell you to root. If you do root and decide you dont like it, just flash a stock rom to it and youre back to normal. But I'm almost sure you won't go back.
