General Rooted or not rooted

view story

http://androidforums.com – Hey everyone new to the forum but not forums in general. I searched but didn't really find what i was looking for so here goes. I have the droid razr maxx and im wondering if its a good idea to root the phone? I have never rooted a phone before so this would be my first time. Also can it be done from the phone itself or will i need a pc? (General)
