I wanted to comment Jonos thread regarding the spontanity of shooting with different formats...and the sometimes "static" MF images.
I agree that it can be a problem to start having the priority on technical image aspects and loosing some spontanity with MF, but I think it does not necessarly has to be the case.
Specially with the S2 I feel very flexible (with maybe the exception of not having superfast continous AF and high ISO). I feel to see the subject very good which is important, I feel to be able to play a lot with shallow DOF when I want to, I feel the sensor allows to play with contrast/shaddow/light, the room for cropping (because of high resolution) lets me tking images quite fast without having 100% correct framing. Most of the images come out as I thought they would come out. Also an advantage of primes that I do know my lenses and which "look" I achieve with them.
In comparison for example with the EP2 and a zoom my vision is not so clear, I can not see the subject as good when taking the image, I do not have such a good feeling which sky I can "catch" and which one I will blow out (or get to much noise in the shaddows), also with the many switches and menues I feel unsecure if I have all settings right.
What I mean, as funny as it might sound, I feel faster and more spontanious with the S2 then with an EP2.
There are times when I prefer a smaller camera like the x1, M9 or K5 or want the fast AF of a D700, but there are also times when I prefer the S2 even for subjects where I dont need the resolution and IQ - just because it works better for me as a camera.
I dont know yet, but with the M9 and K5 I feel they are both spontanious cameras for me, with an advantage for the user interface of the M9 which I just know better, and the plus that I dont have to worry about lens quality, and more flexibility regarding f-stops vs. the K5 having more room regarding high ISO and Tele-lenses and AF (sometimes).
What did I want to say again?
I think I wanted to say: Jono, I am convinced that the S2 would not make you producing less interesting or less spontanious images
So IMO more a question of the photorapher than a qeustion which gear he uses.
