I always thought it was partly\mostly intentional of Leica to alienate people so as to keep up the appearance and brand recognition of being a "luxury camera" with "exclusive clientele". Whatever that means. Maybe Lenny Kravitz or Brad Pitt can fill us in 😉
That aside, I really dont care about any of that, nor even really the image quality (good or bad), and old tech. To me, growing up with other film rangefinders (yashica gsn, various medium formats, etc) and very recently getting back into photography with the digital "rangefinder" fuji's, did nothing more than reaffirm all I wanted was a real rangefinder.
Like any camera, the 240 has its quirks and shortcomings, but it certainly is a very fun and engaging camera to use, for me. When I go out for "results" shooting under pressure, such as going on a big trip with a tight schedule, I'll generally grab the fujis because of the WYSIWYG of the EVF's and generally faster operation, but when I go out to just enjoy the physical act of photography, there's no question in what I take. That's not to say I can't get results with the Leica, it just saves me a few seconds when I hit the play button on the back, change a setting I have assigned to a function key, or when I need to keep things lightweight.
Any digi camera will have a shortened lifespan compared to a film camera, and I really dont think that's a totally fair comparison. However, of all the companies\cameras out there, I might have the most confidence in being able to get a totally new sensor installed in my M240, in 15 years, than anything else out there. Granted it has had its share of issues, but it does sound like there will be a good amount of support for the M9 sensor for a digital camera thats now already 6+ years old. I really cant think of too many other things in the electronics\computing\hardware side of things that has that sort of support, certainly not even Apple feels the same way about their things.
