Ive used this (and LX1) since they came out. Solid, dependable and small. The ricoh is delicate i've heard.
In the past, I have used the GX100, and the G9. The GX100 is a very useful camera, well thought out, and dependable. The fact that it shoots DNG RAW makes life easier too. However, there was thing that annoyed me very much with the camera: when zooming in or out, in aperture priority mode, the set value for aperture would change!
For instance, lets say that I am shooting at f/6.3 at 24mm; then I zoom to 50mm, or 70mm, and the camera would change the aperture to something like f/8. If I choose one aperture (and one that is above the minimum value for aperture at telezoom), I want the camera to stick to it, not change it due to some sort of black-box calculation that is going on. So, aperture priority a la Ricoh GX100 did not suit me. Of course you can use manual mode, but aperture priority is my prefered mode of shooting. It was mistifying, but I got tired of having to waste time returning to my chosen set aperture, after zooming in or out.
As for the G9, it is a typical, solid Canon camera, what the G7 should have been in the first place, with RAW. One can see that Canon is in the edge, undecided as to whether or not to keep RAW in its top tier compact cameras. Of the big names out there (Nikon, Pentax, Sony) it is the only one that still offers RAW. Ricoh, and Panasonic/Leica are fringe brands, but offer RAW, perhaps to attract disenchanted users of the other brands. In the end, the G9 lens stops at 35mm, and I missed the wide-angle.
Which leads me to the LX2/DLux3 camera, from Panasonic (both cameras are made in Japan, even the Leica one, not that it matters for me, but could matter for somebody else perhaps). I have recently bought the DLux 3, just because I prefer its more subdued styling (personal preference). This is a camera that is now more than 1 year old, but it has everything I need for my travel/reportage photography, so I am quite happy with it.
