I think the downside of ALL of the digital cameras is the printing of the pictures.
Now if you are keeping them in electronic format then there is no real problem, but my experience with printing photos is that the ink-jet printers, even with the correct photo ink and the correct brand photo paper is that they fade if they are exposed to too much light.
I tried Canon and HP photo printers that used ink technology and experimented with their brands of ink and their brands of paper and all of them faded. I found that generic photo paper was the worst. I found that HP photo ink + HP photo paper was probably the best, but it was still what I consider unacceptable.
I now use exclusively a Canon Dye Sublimation photo printer. I'm on my second unit and have been using them for 2 or 3 years. I see no fading at all. At least no more than I see when compared to 35mm prints that I get professionally developed and printed. The little Canon printers are available in a couple different models, they do NOT use ink, and are great if you hope to keep the pictures around for your great grand kids to view.
I believe there are a couple other brands of Dye Sublimation photo printers available. But if you are considering a camera, you should also consider the printer, the paper and the technology to keep those pictures around for a long time.
