Rem i dont want to sway you into rooting but...
Once you root, flash a different rom and do smart under/overclocking youre battery will be rediclously good, then remove the bloatware, get free tethering, and have the ability to change ANYTHING... i dont think being stock unrooted will be appealing at all to you.
If youre worried about bricking/damaging your phone, take a look at these forums for brick/damaged threads (theres none LOL), and take into consideration how many people root and how little problems there is that cant be solved personally or with the help of the forum. AND unrooting is SUPER easy.
Like i said, im not trying to sway you.... hehe
