Can anyone tell me the difference between Watery, Honeycomb, and Cyanogen? Is it just cosmetic, or do they perform differently? I have a rooted 7015a and love it, I use it for business and want to get the most out of it that I can, appearance is less important than function to me. (Although appearance is still pretty cool I am not a techie, so simple laymans terms would be awesome! Thanks!
