Also dishwashers are not good for roommate arrangements because unless strict rules are enforced things keep piling up in it or you cannot put stuff inside while it is running. Still have to hand wash it yourself then.
I can see the utility of dishwashers for single people or couples who don't cook, but honestly I haven't found them very useful myself.
Also if you get proper bluetooth headphones and enjoy podcasts, washing dishes can become one of your favorite activities, like mine.
