Many use the Leica M9 (or any other M-series) for street / portrait / candid photography. I also see lots of questions about the M9 in combination with nature / landscape photography. No idea why they ask these questions, because the Leica M-system is just as capable of shooting landscapes as any other camera.
The first photo is an 8 photo panorama shot from the hand (in manual mode). The second photo is a 3 exposure HDR (-2EV, 0EV, +2EV). Also shot without a tripod.
So, if anyone tells you that a Leica M-system camera isn't suitable for anything else than street / candid / portrait / documentary photography doesn't know what he/she is talking about. The limitation is the photographer. Not the equipment.
