I'm coming from the Moto Droid 1 to the Thunderbolt. Had it for almost 2 weeks now. Never rooted my D1. From what I understand some of the benefits of rooting the TB are being able to delete the bloatware and possibly being able to increase battery life. I'm not in a 4G area, in fact 2 hours away from it and VZ not expecting 4G in our state before 2012. So what are the other benefits to rooting? Custom Roms? I don't even know what they are. Similar to skins I guess? What are the other benefits please? Any negatives? Opinions appreciated.
