Like that.
Also, with a bidet, there's no bits of TP that stick.
I've overcleaned with TP and wound up hurting myself, but my undies are sparkling after using the bidet regularly.
Well, Nintendo doesn't do it as much if only because they've got the Apple Mentality that different is always better, even when it's not. Sometimes the best route is just to use what works rather than try to reinvent the wheel, and sometimes they reject new tech because they're afraid of it or because it means they'd have to team up with partners that may not agree with them (like Sony back in the day.) They do copy quite a lot, though.
