1. I need to be prepared that suddenly there is a need to "pause" after taking a few shots. The M9 decides to shut off or to play dead.
2. The battery will die much sooner than the larger battery of the M240.
3. No LiveView option for checking out shimming requirements for some lenses.
4. Smaller screen at back of M9.
So points 1 and 2 make the M240 a better workhorse for high volume, or rapid shooting, then, while the M9 is OK for less intense, more casual or leisurely shooting. I haven't run up against these limitations with my M9, with my shooting style. If I had, I guess I would be scheming for a way to get an M240!
Point 3 would seem important for trying out non-M-mount lenses that have been adapted to M-mount. I can see how it would allow testing the lenses on-camera (your 15mm Hologon comes to mind).
Point 4: The screens on some of my other cameras, like my D700 and X100, do seem better for reviewing my shots. It may be the resolution, and not the size, that I find suboptimal, though. And the M9's histogram sometimes displays as a nearly flat line across the bottom of the graph. I never saw another camera do that, and have no idea what to make of it.
Overall, despite the nuisance of being without the M9 for 7 months, it seems to meet my needs for a digital Leica M. I didn't need it all winter in St. Louis, anyhow! In Florida, that's another story!
I'm sure your M9 will be back by Monday. When Stephanie at Schiller's told me she had received notice mine was on the way, I had it the next day!
