So I decided to buy another point-and-shoot and will probably purchase something like the Canon A1000 for under $200. In the meantime, I also decided to see if my old Canon could fetch anything in the online used camera market, and remarkably someone bought it for about $80. In absolute terms, the depreciation is fairly severe, but in relative consumer tech terms, it's a great price... for the seller. I cannot comprehend why someone would buy that camera (even if it was in great condition) for that price. Art project? Style preference? Scam? Collector's item? Who knows?
I mean it's true that I did throw in 64 MB and 256 MB cards, but that alone can't explain the buyer's behavior.
