It's different because I don't use my ass to open doors, type on computers, prepare/eat food, or scratch my eye. Your face and arms, however, get involved in those activities sooner or later. I don't care if my poop cannon has a bit of residue around the rim that paper can't quite remove, handling shit is literally what it does every day, and it's otherwise stowed away safely.

Granted, I bet a warm-water bidet feels fantastic and I would probably never go back if I had one.
