An MP would be a camera for life. A camera that can work without batteries and has a 30 year post-production service guarantee (so long as Leica are still in business) is as good as any other offer out there. Leica still service 70 year old cameras.

I wonder about the availability of spare parts for digital cameras in the medium to long term. Already, Leica are having to canibalise DMR units because the supply of some spares has dried up (due to 3rd party issues, of course, but there are ALWAYS 3rd party issues)

You also have to consider that batteries may no longer be available for 20 year old digital cameras.
