I chose intentionally obscure and wacky gadgets to overstate the point. I don't genuinely think everyone has these :)

I have had a series of blenders that live on the countertop and are primarily used to make smoothies. My partner had an electric egg poacher, but we lost it in the move. It never got to live on the counter permanently, but I would use it about once a week.

In the era before cheap microwave ovens the electric egg steamer was my go-to dorm appliance!. I found a coffee can would fit in place of the cover. Then it could not only cook eggs, it could reheat Chef Boyardee and Dinty Moore stew cans.
