My wife and I got one this spring and use it for most dinners now and love it. Quick, easy to clean, and the kitchen doesn't get near as hot as compared to the oven.
One of my favorite things we make with it is refried beans. Makes canned refrieds taste like dog food.
I don't know what it is but I find pressure cooking brings out the good flavour in beans, and less of the flavour people describe as "beany" - like a raw bean from the pod would taste.
They also have a smoother texture than cooking in a pot. It's my favourite way to cook them too.
Not "tiny," but the cost/benefit ratio is significant.
