As a younger (33) film to digital convert, I have to agree that people are understating the requirements of switching from film to digital. From my standpoint:
1. Image quality - Without a computer, a shooter relies completely on the in-camera processing and store 'quick and dirty' post processing. If the shooter is used to Kodak Gold 100, for instance, they may be disappointed in a DP&S.
2. Battery life - Just the difference between shooting 50+ rolls of film on a single battery vs. DP&S battery life can be frustrating for many.
3. Time - I agree that people of any age can learn. BUT, older people value their time differently. Why spend hours of time learning a new technology that basically provides the same deliverable as the old technology?
The correct decision, in my opinion, lies in the REASON he wants a camera. Is it to have pictures to put in a photo album and on the wall, or is it to enjoy the art of photography? Having been through decision with 5 family members, I can say with experience that digital is not the answer for snapshot style shooters who have no desire to spend time on a new technology...
