The Leica feel is amplified by the viewfinder. I find I actually prefer the GF1 to either the G1 or GH1. It doesn't really do anything better - in fact the viewfinders on the G1/GH1 are much easier and clearer to use - but this is the one I pick up when I'm off to take pictures.
I took this out with the 7-14 and I'm going to try this + the 20mm F/1.7 which I think would make a nice combination.
