An Undesirable
...... Why shouldn't I expect a digital camera to last for 20 years?
A fair question. A digital camera, replete with its necessary batteries, cards and chargers can go on for many many years without any great issue and certainly well beyond the period the manufacturer continues to support it. Personally I get the impression many expect, or perhaps more fairly desire, a lifetime of support for their chosen electronic product which I think we all know simply won't happen. However a lack of continued support and/or parts does not constitute the immediate end of its lifespan. I know of at least three experienced professional press photographers who still provide national and international newspapers with pictures from Nikon D1H bodies and not one of them is interested in dropping 5k on a new D4 when they can make money by 'making do.'
Having said all of the above I would always advise virtually any purchase to be made after much thought about depreciation, continued support/warranty, your personal needs/requirements and available cash. Doesn't matter if it's a car, camera or a marriage...( 😉 ) I've enjoyed using the M8 and M9 but made the very personal decision to sell out of the system and go with the 'cheaper' Fuji set-up even though the same issues are as likely to affect my Fuji as affect a Leica, it's simply a part of owning something that ages.
In the case of the M8 specifically, isn't this a problem that's come about through Kodak's implosion rather more than a decision from Leica to simply stop supporting this product entirely?
