I'm waiting to see the reaction of the new digital photographers (the point and shoot crowd) the next time they have to upgrade their operating systems and find that their cameras and photosoftware are not compatible. The real push for digital photography is not from the old film manufacturers but from computer and software companies. I was told by an employee of one of the larger photo stores in Toronto that you should upgrade your digital camera at least every 2 years with your computer. "You can't think of digital cameras as cameras, they are really just computer peripheral now", is what I was told. I didn't see a "Used Digital" counter in the store.
