I hear people always asking why they should root. Well the usual is for admin rights to your phone, but here's a great tangible: my wife's rooted Epic voice search stopped working (still don't know why), but I tried all kinds of things, unfreezing apps, restoring all the voice app data thru Titanium Backup. Nothing worked so, I'm faced with a factory reset (if you are unrooted) or a restore of a Nandroid Backup, which was a very recent cloned backup of her phone when everything was still working. I did this thru Clockwork Mod Recovery (a custom recovery you should install as soon as you root). I did the Nandroid Restore, and the whole fix lasted maybe 10 minutes. Did not have to start from a factory phone and reinstall apps, etc.
