Re the F30 / LX1 comparison:
It's true the LX1 has RAW and the F30 doesn't, but that's more or less balanced out for me by the fact that the F30 has *much* less noise (you can check out the comparisons in DPReview's reviews). I pretty frequently have to crank up the ISO to 400 or 800 because of low light (redwood forests, rainy days, etc.), and the LX1 looks awful at high ISO, while the F30 looks far better than anything else in its class (according to DPReview, and evident in their sample images). The F30 is also a smidgen smaller and lighter, and I'm trying to keep the size and weight to an absolute minimum so that it will fit in my purse all the time (after all, for serious stuff, I have a D200, but I'm not always carrying it around with me).
The LX1's 28mm end could be nice, but it only works at the 16:9 aspect ratio. Me, 99% of the time I work at 1.5/1 aspect ratio, and, cropped to that aspect ratio, the two cameras have pretty much the same number of pixels.
The only reason I'm dithering at all is the LX1's RAW capability. But, right now, I give it an 80% probability I'll go with the F30 when it comes out here, and learn to live with high-quality JPG instead of RAW. If ISO 100 were usually enough for me, however, I would probably go with the LX1 instead.
