In the early days of digital photography, memory cards were quite expensive, but the tradeoff and justification when compared with film counterparts was that the memory cards were reusable. You could fit a bunch of shots on your giant 16mb card, then download them and reuse the card, which made up for the fact that the card was far more expensive than a roll of film.
Not anymore. Over on photostream, Colin Jago points out that average-grade SD cards are now cheaper per-shot than traditional film.
I’m not sure this really changes anything, but from the perspective of cost analysis of digital vs. film, the disposable film is now more expensive than the reusable memory cards. Knock on wood, I have yet to have a memory card fail… but at these prices, I won’t feel bad about having to buy a new one.
