My kids have one of those instant cameras with a thermal printer, and you get instant black and white prints, and it's a whole different experience of taking pictures. You have to take the limitations into account, think about lighting and contrast (the printer mangles photos so anything underexposed or overexposed ends up straight up a black or a white blob), the framing (you can't zoom or crop or rotate the photo in post), and people love getting a little physical photo so they agree or even ask to pose for photos, and at least until the novelty wears off it's more fun than just snapping pics on a mobile phone.
