My Roomba is one of the few pieces of technology I own with no downsides to my life. I often think of it as an example of technology done right.
I think it's when you put a screen on anything that it starts the downhill slide.
Helps me to stay in shape, to have a resilient toolbox and to lower my energy bill. I also dislike the noises of many electric tools.
My battery-powered drill stays with me though, as it is just too helpful.
