I just bought an X100T. I nearly bought myself a used Leica M9 with a 35 f/2 but the Fuji X100T fits the bill a lot better. I previously owned an M9 and loved the usability of it, particularly the shutter speed and aperture dials which are nicely visible when you glance down at the top of the camera. But it's a fairly bulky thing compared to the X100T, and pricey at £3000 used for the body and lens.
So, I passed on the used Leica and wandered into the Classic Camera store in London and was captivated by the X100T (I only went in to have a browse). So I ended up with a silver one and it's lovely. I'm still getting to grips with the different config options, but with it's very usable viewfinder, visible aperture and shutter markings, and small size, it's going to be super I know. The auto-ISO setting is brilliant as well - Fuji seem to know what they are doing.
I have a Sony A7R with a few lenses as my full frame option, and the X100T is now my pocketable take-anywhere camera. And it's lovely to use - a similar experience to the Leica albeit with autofocus, nicely placed viewfinder, and the ability to set it up just how I want. Nice.
