Well, it's pretty obvious the advantages of rooting a phone. Titanium Backup being probably one of the biggest reasons in addition to Ad Blocker apps. The ability to theme or mod certain things that maybe you couldn't do otherwise. So, that's why. Yes she does mostly text and call and Facebook but she has a lot of apps and things to restore and rooting it makes it easy. Not that it's any of your business anyways.
Life Lesson: listen first and speak second. There is often a good reason for something. You may never have thought of.
Now, she does have the camera widget which was my first thought, but she says that's not it.... And it opens other times as well.
