I got the X100 yesterday, this is one neat little camera!
I ended up paying 2200RMB (~$350) for it after selling my GH1 and the two olympus kit zooms. Came with the Fuji lens hood, which is apparently made of solid silver since Fuji sells it for $99 new, so that was a welcomed addition. No lens cap though, I found one online and will order it during the week
Now for the camera in itself, it's one sexy beast that everybody confuses for a film camera, I guess Fuji did a good job on the retro feel!
The body just feels awesome in hand, it just gives that feeling of quality that's missing from the E-PL2, everything is perfectly fitted, nothing rattles or squeaks. Thumbs up to Fuji for build quality.
I've been using it yesterday with the Firmware in version 1.11 (quite early then) and while it was definitely a bit sluggish at times, I didn't find it as annoying to use as most people say, especially in terms of AF speed, but I think most of the people that were complaining about it came from DSLRs, not from the not-that-quick E-PL2. The firmware v1.30 does speed up everything though, AF is snappy -still not DSLR quick, but really quick enough- and the UI feels quick and responsive pretty much all the time.
IQ is awesome, colours are quite different from the Olympus but they are really quite pleasing and the lens is really sharp, even at f/2. Low-light performance is terrific up until ISO 3200, ISO 6400 is quite noisy, but I think more usable that the E-PL2 at 1600 with a quick cleanup. It's so good that I ended up setting up Auto ISO at 3200 when the shutter speed drops under 1/15s, so I don't have to worry about getting the shot in pretty much any conditions
I've been mainly using it at night (lazy sunday FTW) so I can't comment too much on the daylight handling. I did try to get a few shots from my window and there will be a slight learning curve I think: While the camera is capable of 1/4000s shutter speeds, it can do it at every apertures, for instance f/2 is limited to 1/1000s of a second, f/2.8 is limited to 1/1300s I believe, etc. Thankfully Fuji put a ND filter in that thing, so that should help quite a bit in really bright days
The OVF is awesome, the info overlay is really brillant and can be setup pretty much any way you want. It's quite dim in lowlight though, so the EVF is definitely a welcomed addition. I feel like the EVF is slightly inferior the Oly's VF2, more on par with the one from the GH1. Colours don't look that accurate in it and there's quite a lot of grain when used in low light.
The "macro" mode is kinda useless, because of the parallax error when used very close it switch to the EVF by default, it doesn't focuses very close too (~10 or 20cm I believe). In short, the E-PL2 with my Nikkor 55mm macro lens still has the upper hand there. Not a big deal since I didn't buy it for that purpose
The battery charger is also a joke, somehow Fuji thinks it's OK to sell a camera with a charger in which the battery doesn't actually fit. The battery is too short so Fuji bundled a small piece of plastic with it, that piece is not attached to the charger or battery so of course it got lost in the guy's shop. Right now I'm using a button to hold the battery in place. I'll glue a small piece of plastic in it so no big deal, but it still seems weird to me that they would do such a thing.
All in all, very impressive camera, I already love shooting with it!
Edit: I just ordered a lens cap (looks legit) and a cheap lens hood since the shitty UV filter that was bundled with it is currently tightly screwed and stuck on it
