Ouverture:
I beg to differ. Because some people uses Live View more, and especially on the GF1.
Hence they might require more battery per trip. This need to be taken into consideration especially
when GF1 did not have built in viewfinder. Maybe you have left this point out.
Personally,
I think the higher tech the equipment is, the more battery juice they need. My 20D can last 2 full days outdoor shoot with no problem. I do sport shoot.

But when I keep checking my picture with the display when doing personal shoot, after 30mins shooting time my battery will change to half a bar. And I do use battery grip as well. So Live View in short draws alot of power I assume. (20D no Live View, just checking pictures only!)
Besides, most review site will state the number of shots with VF and LV and
you can see with LV the number of shots is reduce as much as a whopping 50%.
Regarding their quality, I cant say. Because I didnt own any of Pany camera and DSLR. But if their quality is as good as Leica ones, then I sure will pay for that amount. But GF1 is still a machine built DSLR like any DSLR, just that smaller. Better then P&S, that really depends on the user.
Because I have seen people work with P&S really beat my pictures hands down with 20D. :embrass:
