Many years ago, in a lifetime far away, I did commercial photography. I made a series of very high quality 35mm film strips of needed documents (used kodalith film with nikon macro camera) and carried them in a 35mm film can. Used with a good commercial eye loupe maginfier they worked very well. Until they got wet...... The emulsion on film is not water resistant and will quickly scratch or slide off the backing.
As a result, I now carry my data on a palm with 256megs of removable storage. Agreed, not bomb-proof, but works well for me. Easy to update and all that. I have carried a palmtop through mayhem for over 10 years. Have yet to have it fail. Which means of course it will die today. But the media is removable and can be loaded into any PC. I think the media (Compact Flash Card) is much more robust than film. Even the palm is better than film (in my opinion). we have two identical palmtops and solar rechargabe batteries in our kits.
