You left out the most obvious question: "Why are your cameras so bloody expensive?"
I am a Mac person, I love high end stuff and enjoy paying top dollar for supreme quality devices. But M prices are just way too much. I just don't see a justification in spending $10-12K on any camera system if its not your profession.
Jesko von Oeynhausen, do you really believe that there's a new generation of young people becoming Leica M system owners? Dono about you, but my kids can forget about getting a $10k allowance for a camera... :)
Leica could have been the Apple of the camera world by taking their M cameras to a realistic high-end price range of $2000-3000. With such price point, their stores would make sense.
Leica, IMO, if you want to grow beyond a boutique shop, its not by designing your cameras to look like colourful toys (just a defocus). It's only gonna happend by re-examining your business model for the new industry and economy that you're in.
