I was bothered for many years by the constant upgrading inherent to digital photography, at least in its early days. Then there was the leica "modul r" that seemed a perfect solution: you'd just detach the digital part and swap it out for the next best one, a few years later. Or shoot film whenever you wanted. Genius! Well... it was quite promptly discontinued; the upfront cost was too much for most consumers and there's just not much profit to be made that way.
Upgrading has been the core marketing principle of digital photography. If I had a buck for every time I read some column claiming that
this one was the one to equal film... and then a few months later, no,
this is the one... etc ad nauseam. Meanwhile people thought 12 mp is twice as good as 6 :rolleyes: Now
that is unsustainable. Indeed, things have improved in dslr land now, but the marketing principle is
still based on higher and higher pixel counts and more gadgetry. (Incidentally, I am not fervently anti-digital, I do have one that I consider to be very nice for several things and it is one of the very few digital bodies that I think is actually built to last, but... it really only handles
some of my 35mm needs)
Anyway, this whole notion of sustainability in the "built" economy has become an irritant to me. As far as I know, no electronics product... *none!*... is fully recyclable. Not even close. (n.b. I have several wooden cameras that are 100% recyclable

) What if we actually factored remediation costs into the prices of our electronica? What would the prices be then? What if your CFL bulb cost $100 instead of $5? (And, to be fair: what if you had to return the silver from your fixer or pay a fine or higher price on the next purchase? Not so hard to implement, actually...)
Until people start computing the actual, upfront consumer cost of sustainability, it's hard for me to take it seriously. I like the idea(l) of course, but, we have to run the real numbers.
