Forgive me for being repetitive, but:
If you need to be convinced to root, DO NOT ROOT! Rooting plays with the core system files on your phone. If you are not sure you want to root (regardless of what anyone else says), then do not do it. If/when you do root, learn what you are doing before the fact. Learn what is going on, what a kernel is, what a ROM is, what the cache is, etc. I swear most of the problems with computers (not just phones, so this is not aimed at anyone here) are caused by people doing something they were not knowledgeable enough to do. You do not have to be an expert, but at least know what is happening and what is being changed.
That being said, I strongly support rooting. My phone is rooted, and I would not have it any other way. I just think that people see rooting as a casual thing to do, and do not treat it as a big system altering operation that has a real (but not necessarily probable) chance at bricking your phone.
Just my thoughts,
