I really like this! I want to see it get a little easier to be carried around, but I want to build one! I'll be able to use my Sony Mavica to take pictures on floppy disks and my floppy-walkman to listen to music from floppy disks!
Now I also wonder what other horrendous uses of floppy disks there could be... I'm thinking it could be fun to store server web pages (without caching)... Or maybe to play some video feedback?
