damn, just wrote a book and then mistakenly reloaded the page. all gone.
so, to keep it short:
bought one, sold one, bought one again, used it for years, recently found a black one at a good price, bought it, gave the second silver one to a friend for traveling middle America for two months, sold it to him after he didn't want to give it back, bought a Ricoh GR (V), am partly happy about it, now got an R-D1s and don't know why I'm always jealous looking at my black X100 in the hands of my girlfriend, she smiling.
Buy it! Colors are just great, noise rendering is beautiful and very usable up until ISO 1600. It's well made, it's a beauty, it's always there for you!
If you want to know what one can get with it, please have a look at my website, almost everything was shot on this camera (except obv. the Instax and the grainy b/w, that was misdeveloped Tri-X)!
