Thought about rooting all my devices back to the OG Droid and never made the move. More out of lack of time and interest in trying different Roms than anything else. Sure, getting rid of the bloatware would be nice, but now I just hide ask the apps I don't want to see and then ignore the updates. As for themes, Nova launcher and UCCW have provided me with nearly unlimited options. Also, I've not come across an app that I was interested in that needed root, so it's stock for the foreseeable future.
