I'm changing the header slightly. Perhaps other may contribute further. In a message dated 12/1/2011 1:06:28 P.M. Eastern Standard Time, lawrencehelm@xxxxxxxxxxxxxx quotes his message in another forum: "According to Wikipedia "Planned obsolescence or built-in obsolescence in industrial design is a policy of deliberately planning or designing a product with a limited useful life, so it will become obsolete or nonfunctional after a certain period of time." The argument was recently made that all E-System cameras except for the E-5 (which is still in production) are obsolete. Does that term apply in this sense? I don't think so. I see no evidence of E-System cameras failing in an abnormal manner. They are all still in use and performing as they were designed to perform as far as I know. "In looking for the origin of the term, the writer of the Wikipedia article says, "From that point on, 'planned obsolescence' became Stevens' catchphrase. By his definition, planned obsolescence was 'Instilling in the buyer the desire to own something a little newer, a little better, a little sooner than is necessary.'" ---- That is interesting, and I wouldn't be surprised if the OED picks this up. It's technical enough. Planned obsolescence. "The term obsolete is far too harsh a word to apply to all the differences or "improvements" that appear in cameras later than the early E-system cameras." "I'm not really looking for Helsinki to respond to this note. I would be more interested in responses from the people justifying their moves to different or "better" cameras." ---- Good. I wouldn't know. There seems to be the wrong implicature when it applies to 'obsolete'. Note that the etymology is never certain. There is this idea of 'solent' (as in INsolent), so if it's obsolete, it's no longer 'practiced' (or 'produced'!). This is different from 'extinct' (as in the auk, an extinct bird). ----- The idea of 'planned obsolescence' is a good one. Not in the sense of Locke -- as per what the idea _represents_, but as 'idea' per se. Very tricky. ---- And so on.
