One of these days we'll all have to use emulators or hardware clones, even for our PC's we have now. I'd rather just use it and enjoy it, than put it in a box where it is still going to age anyhow. Rather have the experience than worry about the air and light touching it and never enjoying it.
I don't get the collectors that just keep things in the package, I think they are more "historians" of a certain product or company than "collectors" who enjoy the experience of using the item.
I'd be guilty myself of going back in time to the 70's and living there forever however. I suppose we all have our "thing".
