Regarding your other statement with DOF:
I have encountered one critical thing with my G3: As good as the EVF is I sometimes shoot a scenne and find the focus plane to be slightly further back or closer than I would want it.
I think its sometimes hard to judge when looking through the viewfinder. Maybe I should sometimes switch to magnification even when shooting with AF.
I seldomly have this with very large viewfinders and the AF of the D700 or the S2. This may also be a result of relation between AF-point-size and image sensor size.
Even with some DX sized sensors (K5 and Canon 7D) I have not been lucky how I could focus precisly where I wanted. (For some reason the D300 it worked fine for me).
I have the same problem with the G3 (and had it with the EP2).
The "Spot"-focus of the x1 on the other side works very good for me.
What I am trying to say is that for me I have encountered that I can live with pretty shallow DOF for many things as long as the focus is 100% accurate. (For example on the eye of a bird). The less precise the AF can be "targeted" the more DOF I seem to need.
Of course there are also many subjects where one wants more DOF anyways.
