themacguy: I own both the S9100 and the S100fs. Both are excellent, IMHO, for the use I intended. The only things I didn't like about the S100fs were the proprietary battery (I prefer AAs - who doesn't?) and the fact that the histogram can't be set to stay on without depressing the +/- button. Otherwise, I'm quite happy. I skipped the HS10/20 units as I didn't feel there was enough improvement to warrant another purchase at that time. I'll wait for the X-S1 to come down in price a bit (and be thoroughly debugged by the early adopters). Too bad about the continued use of proprietary batteries in the X-S1.
Agree 100%. I started in digital with the S1000fd and then moved up to the S100fs. I still love using it and the results it provides.
I looked at the X-S1 in a camera store this week and was VERY impressed. In fact, this was the first time in 4 yrs that I have ever even be led to consider an alternative to my S100fs. However, I probably won't be making a move until my S100fs fails on me.
