I definitely do have large hands. I mean, my fingers are a normal width so I can easily manipulate dials and small buttons. (I can type fast on an iPhone, that's saying something!) While I do prefer the physical feel of larger cameras, I can still work with small ones.
You both bring up interesting points. I pretty much only shoot the D-Lux 4 in RAW, but the few jpgs I did do ( in dynamic B&W ) were absolutely outstanding!
I certainly am very very partial to the camera, I love it so much more than the Canon G7 I used to have. I still do like the G10 a lot, but I prefer having the 24mm f/2 lens.
I am well versed in IQ in relation to megapixels and sensor size, pixel pitch, you name it. So I'm pretty comfortable working with most anything. I have just been intrigued by the G1 (and the forthcoming Olympus) as a dream small camera.
If I could change things on the D-Lux, I would make it a 24-105 lens, and I would have it not be a zoom, but rather "selectable focal lengths" akin to Leica's Tri-Elmar lens. How awesome would it be to move between the major FLs. 24/28/35/50/85/105. Then you would know exactly which FL you were at instead of trying to guess.
I guess the only thing holding me back is the fact I'd have to buy lenses for the G1, and I'd have to start buying M mount lenses which will get me into big trouble! (I've been down the M-system road before!)
Thanks for your input guys, I'll probably just be keeping the Dlux4 and be happy
