At a party last weekend, I got carried away with one of these little instant, polaroid-like cameras that spit out fun images in a totally non-digital, old school way. Sure it's fun to take pics with your camera phone and send them by text or email, but if you want something that you can actually hold in your hands and pass around a party, this is pretty cool.
I did a little research into FujiFilm's whole line of Instax cameras and there are a whole lot of options and different price points. The easy, fun, toy-like starting point would be with the Instax Mini 8, but if you bump up to the 50s, things get a lot better. Both are small and easy to fit in your bag. If you want a good review, check out this one over at Wirecutter, where the pros and cons are all well outlined. Here's also a lovely little blog post about the camera from RaySnaps.
