I'm not quite sure why my MP is now obsolete because of the M9.
I'm not sure either (and don't sympathize with a claim like that), since it's hard to say what obsolescence is. Both film and digital fans bandy that term around (usually in disparaging references to the other group), but it's pretty amorphous. As I see my own equipment, the 120 cameras are definitely technologically obsolete but are far more useful than the digital equipment.
But to the point - one reviewer [who will remain nameless] uses this definition: "replaced by another model." By that logic, the M8 and 8.2 are obsolete - and so are the M2, M3, M4, M5, M4-2, M4-P, M6, M6TTL, M6J, and M7. Note that prior to the D3, though, this particular reviewer disparaged the long-desired 24x36 sensors as following the size of "obsolete" 35mm film - and did a 180 upon discovering film scanning. When the M9 came out, the reviewer then said the M8 was obsolete because the M9's sensor was full size. So I guess things can be obsolete (24x36mm framing) and then be posthumously rehabilitated?!
Ok, enough anecdotal stuff. Since I don't know how to precisely define obsolescence, I looked in a dictionary. These were the choices:
"No longer in use or fashion."
Film cameras are definitely out of fashion but still in use. So this one is inconclusive.
"No longer used or useful."
Film cameras are both used - and to some people - useful. So not obsolete by this standard. My four Fuji medium format cameras, my Autocord, and my Noblex thank the American Heritage Dictionary.
"(Biology) Increasingly vestigial or disappearing in each succeeding generation."
Guess it's a good thing we're talking about cameras and not living things!
At the end of the day, I think you can boil the concept down to one or more of three things:
1. Does it utilize the most current technology?
2. Is it useful for its intended purpose?
3. Does the market value it?
So when you see these discussions, different people are probably talking about different things. I think it's a losing argument for film zealots to talk about "obsolescence" (writ large) because film cameras fail the first and third definitions. By the same token, digital bigots should not throw stones because digital products are always falling behind in the same two definitions. That leaves the "is it useful for its intended purpose" criterion - and frankly, no one should be lecturing anyone else about such a personal preference.
