I am a strange collector. Nearly all of my collections are things I use or mess with. I did get some Everdrives so I don't have to swap cartridges so often. Even most of the toys and such that I "collect" are out of the package and played with. Maybe I am not a collector. I just don't see the point in having things I like if I am not going to use them. I even handle my sculptures and other art.There are two types of people who will be interested in purchasing prototypes. Collectors and avid users.
