I don't know whether I'm missing the point altogether or not. When I upgrade either my computer's system program or my suite of working programs, I very often need quite a bit of time to get used to the new environment. Not only do I not find that dramatic, I actually take pleasure in the challenge (where have they put this? Oh, there!). The X100 is a bit of the same, only much simpler, because there are far fewer places where Fuji could hide things (the menu tree is basically two dimensional), and the rest is all buttons. So I'm spending some interesting time getting to know where things are - and taking rather good pictures in the process. It's a very good camera, and complaining about the software is a bit like complaining about the Ciba process in the now distant past; it was finicky as hell, but it produced good results, and I don't remember anyone complaining about it then.
I'm having fun getting acquainted with it. Hope you can all have some fun too.
