I am considering re-rooting ( did it in the past for a screenshot app), and installing a custom ROM, but I'm wondering.. what are the real advantages? My stock Inc2 doesn't feel slow at all, and I basically don't notice the bloatware. Would I get better battery life? Any key features found in GingerBangSense or MikRunny that I'm missing out on? I can only think of tethering off the bat.
