Mr. Callow (any relation to Simon Callow?) I think you are dead on about the horse and horseless carriages. And I also agree that there's another medium sized evolution or two left in film. It is nice to see that Fuji is still in the R&D business when it comes to film.
Hopefully, however, APUG will stand for Anachronistic Photography Users' Group in some distant future generation, far from ours. Just as our generation is pretty far from we collodian plates and tintypes. And just as 24 year olds today drive VW Cabriolets, not having the faintest clue that a Cabriolet is an open carriage.
The avatar is a snowman. A very good one, I might add, brought to life by my four year old son.
