I used Nikon mechanical cameras since the late 60's and went Nikon digital when the D1 came out. Sure it had it's issues but the technology was new. The technology isn't new now however and the issues Nikon, Kodak and Canon had in the early days shouldn't happen now. At least Nikon and Canon didn't take months to get their pros back in business.
I went from the Nikon D1x to the Canon 1D and 1Ds when they came out. I do a lot of product and architectural work and needed the tilt shift lenses. My first 24-70 L series I came apart the second day I had it. The front and back totally separated. I called my dealer that they shipped a new one out that day express mail. Never another issue. The only time my lenses and camera were in the shop was to set back focus. In those days they had to go the the service center for that adjustment. I later went to 1DsII's and never had an issue in eight years.
I understand what you mean about not servicing out of date lenses. I had a 200 f1.8 L the fortunately never had any issues. It was probably the best lens I've ever used for the 35mm format, Leica included. Even with a 1.4x extender it was better than my 300 f2.8L which was a fantastic lens. Canon makes superb cameras and glass as does Nikon. I'm all Nikon digital now using a D800 and Df along with ED glass and primes for the DF. I found the 14.5 stops dynamic range of the D800 to be a significant advantage for interior architectural work.
7 weeks of waiting might be OK for a Leica enthusiast but not for those of us that make a living with our equipment. The failure rate and repair times are just unacceptable.
