THE CRAPPIEST INVENTION EVER: A bad review for auto-flush toilets. “The auto-flush toilet violates two basic rules of technology adoption: Never replace a technology with an inferior technology; and never confiscate power from your users.”

UPDATE: Reader Cathy McCaughan emails: “The reviewer fails to note that parents of preschoolers everywhere loathe auto flush toilets because children find them frightening.”

So in addition to their other faults, they’re scaring our children!
