Sadly, we live in a disposable world, where once the shine off of something new fades, its time to replace it with the latest and greatest.
There are many digital cameras that existed that could be considered "vintage" but they would not be 50-60 or 70 years old, but something closer to 10 or so. The discontinued Kodak pro line comes to mind rather easily. A little ahead of their time, a lot behind in other ways... still, they set the pace in many an area.
We move so fast in this area that things change on a yearly basis that I think cameras that get old enough to be considered "vintage" (30 or more years, perhaps?), won't mean the same thing like picking up a Nikon F2a would be today.
