It's about convenience and freeing up a burner on the cook top. I love the hold warm feature on mine in particular. It'a a zojirushi that's pushing 12 years now

It's about convenience and freeing up a burner on the cook top. I love the hold warm feature on mine in particular. It'a a zojirushi that's pushing 12 years now, and I've never had a single issue with it. It's far from being plastic waste for me, and I wouldn't be surprised if it lasts another decade.
