If I understood you correctly:
I, for myself, think it is harder to choose nowadays, with so many different options out there to choose between.
And I cannot afford to have as many cameras as I want to (and am not allowed either, apparently we have to pay the rent...;-) ). So I have to think of what I need, and why.
Assuming having only one system, I stick to my E3 and the belonging lenses. But then I need a more portable camera, to fill in, and to have in those certain situations when the E3 is too big and bulky, for instance walking the night streets in Cape Town, when on a party where I am not the photographer etc.
Almost automatically looking at the soon to come MFT-system, beacause my photo habits have made me pretty cautious when it comes to image quality and the possibility to handle the camera manually, and the thought of a big sensor in a little camera would kind of guarantee quality. Still realising that it would be a new and parallell system, and to have only one lens (fixed? pancake?) would not have any advantages over a good P&S camera. And there are a bunch of those. I choose the LX3. Could as well have been the Fuji 200 something, or C G10 or the DP2....
I also think there ar many "specialised" cameras, every one good at what they are aiming for, and for the need of the user. So I would not consider any camera be any better, I think the best camera, above a certain level, is the one I use and feel happy with.
I will try to be happy with my Panny, and to see if the somewhat limited zoom range fits my needs (which I think it will do).
We have all different reasons for our choices. In the end one will have to put on the blinders and go for the equipment you have choosen to have. But, I admit it's hard.
