[...] but that’s more of a commercial benefit I think

For me, this is the primary benefit of a rice cooker. Having warm, cheap, filling food on demand at any time is fantastic. I am so lazy and my little rice buddies are always ready to go when I can't be bothered.

I eat a lot of ice and I still just make it in a pot.

A rice cooker can serve as a cheaper instapot tho. I can steam rice and veggies without having to babysit a pot.

I also have kitchen anxiety, and in a roommate situation can keep a rice cooker in my room.
