The old digital cameras will be a thing I bet. Super cheap, super fun. You'll probably enjoy the Mavica. From what I recall it was the first really widespread digital camera.
I rebought a Minolta G400 a year or so ago and it took me quite a long time to find one intact. The 4mp camera was really good in bright light, best at the time, and in low light it was atrocious. But like Brian Eno said, when every generation of technology changes, the worst thing about the previous generation will become it's signature.
I keep old stuff around like a Sony USB floppy disk drive and an old Powerbook. Never know when you are gonna need it! Old technology can be fun sometimes compared to the bloat we have these days.
