This question always comes up, and cannot be answered by any of us. It all depends. First off, I would
not within the first 14 days. Only because if you're unhappy, you can always take it back, but maybe not, if you're rooted. Now, they might not notice it's a rooted phone when you return it, but then again, they might.
If you're just rooting for bloatware, I can certainly understand, but is it a space issue? Because you can hide the bloatware now with the stock OS. You obviously cannot remove it, but you can hide it so you don't have to scroll through it. Also, do you plan on taking updates? If so, you can't remove the bloatware because most of the time the update won't install right without it. So what you do is freeze it, but it's still installed, so once again, I'd just hide it.
Anyway. That's my opinion. Will I root it? Probably, but only after the 14 days
