We rented a house recently that had a toilet that had a number of features. It had a heated seat and water, wave your hand and the lid lifted or closed automatically so you didn't have to touch it, it would rinse your front or backside with a preset water temp, auto flush, and a bunch of other shit I can't remember.
I thought it was ridiculous when I first saw it, but after using that heated seat one time I was loving that thing. I wasn't brave enough to try the rinse features LOL.
Never having to bend down to lift the seat was really nice too.
