Man of Honour
I'm not sure about that. Despite the M9's interchangeable lens I always ended up using the 35mm Summicron F2. I just seemed perfect for this type of camera. The fact that Fujifilm have chosen the same specification fixed lens speaks volumes.
Anyway, I'm having one as soon as they are available. I love the simplicity and the hybrid viewfinder looks like a real step-up from the M9 rangefinder. The X100 is a supplementary camera to my DSLRs, and for that purpose it should do well.
It is a lovely focal length no odds and good for most shots, but personally, spending that much I'd partly want the flexibility but mainly the ability to take the glass forwards to a newer body in 3 or 4 years time (it's a 35mm f/2, it's likely account for 20-25% of the value of the camera - shame not to be able to keep it).
I do see why you want it though and I'm sure it'll suit you down to the ground. I'm not questioning that it's good, just that it's good value...
