Thank you all again for the kind comments.
The X100 certainly can deliver the goods and it's size, weight and nice tactlle operation make it easy to use in "Auto human mode" as opposed to "Auto camera mode", I can set the camera up as I want it and just pull it up quickly to me eye to compose, allow autofocus to do it's thing (I am convinced this is a fair bit faster since updating to firmware 1.13) then press that silent shutter - job done.
I also find that I am using the X100 as I did my Leica Rangefinder and by that I mean, I am previsualising the end result a lot more, being more thoughtful with my settings and in turn shooting fewer images but having a higher percentage of keepers.
I have also got to the point now where I have turned off the post shoot image display so that I have to make the camera display the image taken only if I want to check it, this again helps reduce overall shot to shot time and allows me more time to look for the next image.
All in all I am sure you can gather that I am delighted with the performance of this camera and the end results, as long as people take the time & effort to understand the camera and it's idiosyncrasies it will provide end results that really please.
