I was expecting to trash the idea of custom roms for the laymen, but this is actually a really smart idea. In this case, "minimal" means "as close as possible to a dumb phone", which means uninstalling everything that's not the phone app. I'm not sure how much longer society will tolerate somebody with a phone that can only call, but for those who truly only need to be able to call and text I think it's a brilliant solution.
