I picked up a used X100 last year and I really fell in love with it, despite it's finicky menu. I actually did a minor upgrade and picked up an X100S (I say the "S" stands for "Sid Edition") while hooking a friend up with the X100, and then later helped another friend pick up another used X100. I seem to be in the market of helping friends get awesome used cameras :)
I recently picked up a Fuji Instax printer to play around with. My X100S has a built-in wifi feature that will work with Eyefi cards, so I've been shooting with the Eyefi card, which uploads those images to my cell phone, and then I can print those images on the Instax. It isn't as easy as just pulling an instant print with my 4x5 or Hasselblad cameras (or even one of the Polaroid Land cameras I have lying around) but it's still pretty neat.
The X100S is lovely. Just like the X100 before it, I recently shot a majority of some assignment photography for The Hippo using just the X100S. I freaking love this camera.
