Mani, you're correct, I am very enthusiastic about the M8, as keen as mustard as we would say here and I am planning to buy two. That doesn't mean at all I think Leica can do no wrong.
Most of all, I want the M8 to deliver outstanding images, but I also want it to be an ergonomic success and my fear is that with memories of the M5 and the opinions of Leica traditionalists in mind, they have gone for too minimalist a design with all the digital "stuff" swept under the LCD/Menu/Buttons "carpet". This camera will miss the point if the user has to page through menu after menu to change a common setting and miss the photographic moment as a result.
For example, to change ISO on a D2x, press a button and click a dial. To set EV+/-, press a button and click a dial, and so on. How easy will these operations be on an M8?
Even if it is an ergonomic dog, I will still buy the cameras because I think Leica deserve my support - I'm a fervent believer in precision value-added manufacturing and I don't subscribe to the view that you can build an economy by flipping hamburgers and selling each other life insurance.
I do understand though that for all sorts of reasons, the M8 is a very significant purchase for many people and they want to wait and see and that even then, there are higher economic priorities. In the meantime, they can see how people like me get on with the warm glow of schadenfreude when it all goes wrong...
