I just got the Fuji (I still call them that, don't know why they changed it to "Fujifilm") X10.
The reviews so far (I've read a long one in the non-online (except via Zinio) edition of Amateur Photographer) are very positive indeed. And from my short tests so far, I agree.
The camera feels great, the usability seems really nice, it's quick (one forgets the "old" days where every compact camera was slow as molasses to focus), the image quality is real damn good, even in the one area you think it might be a bit weak due to the smallish sensor: low light. (The sensor is smaller than those in exchangeable-lens cameras, but larger than other compact cameras like Canon's G12.)
It's large enough for good handling, but small enough for a large pocket (a jacket pocket or a side pocket on "combat" (cargo) pants.
The manual zoom on the lens is really nice, faster and more precise than the motorized zoom used on smaller compacts.
It is not cheap of course, around $600, but rather less than the X100 at $1000, which sells well though it's more limited.
For years we have been getting closer and closer to what Mike Johnston and myself and others wrote about longingly for years: the perfect street-camera. (Johnston calls it the DMD, the "decisive moment digital", though he prefers prime lenses.) It should be compact, and fast, and have image quality good enough for exhibitions.
A camera like the Panasonic Lumix GF-2 comes very close, except one thing: due to the sensor size, if you put a zoom lens on it for all-round use, it is no longer so durn compact, don't fit in no pocket, no sir. So, not that universal. Fuji's own X100 has the same issue: it only has a slightly-wide lens, though it is compact for its large sensor.
I have tried cameras like these with fixed-length ("prime, non-zoom) lenses, but I just miss the zoom too much. I am really the happiest when I have a normal zoom from modest wideangle to modest tele.
And the X10 has just that: 28mm to 112mm. And it's fast too: F:2.0 to F:2.8. Very nice.
So I hereby declare, admittedly on slim evidence, that the X10 might be the best all-round, street-, or travel-camera we have seen yet. It has image quality similar to larger-sensor cameras, but it has a zoom and is yet in the big-compact class. This is quite exciting for a certain class of enthusiast photographer.
The one weakness I've heard about so far is the smallish battery: only maybe 250 pictures to a charge. A very active photographer might want to bring a backup battery. (The battery is really physically unusually small. They must really have struggled with space in this camera.) Fortunately this is not expensive.
A note: in my brief testing, the X10 has surprisingly good image quality for a compact, even at 3200 ISO. This is a big accomplishment, even the older Lumix GF-1 with a much larger sensor suffered at only 1600. And older compact-ish cameras like my old Nikon 2400 from six years ago, had awful, dreadful noise at anything over ISO 200. Even 200 was noisy. This is a revolution.
And it gets even better, due to a special sensor with 45-degree angled pixels, Fuji has a pixel-doubling technology ("EXR") which if selected on the mode dial drops resolution to a still very useable 6 megapixels, but markedly improves fidelity in low light or alternatively in high-contrast situations! (You can set this to auto, and the camera decides which setting is the most called for.) This is very useful technology.
In fact this technology is used in several different ways which all seem promising. Normally I'm one who sticks with default settings, but I think these may be worth using in many difficult shooting situations.
I admit that the advantage in using the EXR technology is not always crystal clear, and it would be smart to learn more about it. But here is a couple good examples, hand-held photos (small crops) taken in a poorly lit corner of my living room (normally I wouldn't even have expected to be able to hand-hold photos in such a dark place) :
And with EXR:
Notice how the details (in the leather etc) is nicely preserved with EXR, and the photo is less grainy and sharper.
But like I said, even if you forget about EXR, this camera is probably king of the hill right now for compact cameras as regard existing-light photography.
Again strongly cropped... EXR off:

Update: A few have had problems with white-disc shaped highlights. I just now shot at night, and even though that's just inviting problems of this sort, I only found this one, and not a bad one, hardly noticable I'd say.
