Definitely enjoyable to use although for me manual focusing is a bit slow and awkward. And the auto focus can miss at times.
If you're new to the x100 (and you've got an x100, not an x100s) then you should check that you have the latest firmware update. The latest version is 2.01, and this update improves AF considerably, and MF is also much improved over any of the firmware 1.xx releases, making it quite usable.
You can check which version you have by pressing and holding the DISP/BACK button whilst switching on the camera. The currently-installed firmware version will then be displayed on the screen. Here's a link to the update page.
Hope this helps.
I like using this camera as a digital B+W camera and appreciate that I can set the jpegs for B+W and see B+W through the EVF (and yet still have color if desired in the raw files.) It's visually helpful for me.
