quoting from dpreview, I find it's one of the best sites out there for this. I also think that a LOT of people underestimate how good an olympus camera is!
Ummmmmmmmmmmmmmmmmmmmmmmmmmm.....................................
I hate to point this out to you, but....................................
You're quoting from a
press release, which is not exactly a review. (This is another problem with DPReview, in the quest to appear to have more information than other sites, things like press releases are not cleared marked as such.) DPReview has not reviewed the Olympus 1000. In fact, they have not reviewed any Olympus PnS with more than 7mp.
Since there aren't reviews of the 10mp Olympus to be found (at least, I couldn't find any, but admittedly I didn't look very hard), we can go to DPReview's review of the new 7mp Olympus SP-550UZ, which should have their latest noise reduction and sensor technology. They say, "There's a lot of noise reduction going on at anything over ISO 200 too, and by the time you get to ISO 1600 - the highest 'full resolution' option - the output looks distinctly blurry - despite some fairly obvious and visible chroma noise in the shadows. Included for completeness in the crops above are the two lower resolution high ISO options, 3200 and 5000, which are almost free of noise, but almost free of detail too."
DCRP had this to say about it: "There is just a slight increase is noise when you go from ISO 50 to 100, with a minor loss in detail. At ISO 200 we see more noticeable noise, and once we hit ISO 400 there is a lot of multi-colored noise destroying the details of the shot. At ISO 800 this noise and detail loss is magnified, and by the time we reach ISO 1600 there is virtually no detail left."
Steve's Digicams, which is generally pretty easy on the cameras in the review, had this to say about the 8mp Olympus FE-250: "These high ISO settings also show a significant increase in image noise. ... The camera selected an ISO speed of 1000, which is not even the highest setting available, and the image looks horrible. Not even worthy of being used for a 4x6-inch print. You can also manually select ISO from 64 - 10000. This is by far the highest sensitivity we have seen on any consumer model. However, noise levels are higher than normal, even at ISO 64. At 6400 and 10000 (which the camera reduces the image quality to SQ1) images look as if they had been taken by a camera phone."
Now, if these are the results you're getting from 7mp and 8mp sensors, what hope does the 10mp sensor have? Actually, the FE-250 has a larger 1/1.8" sensor (as compared to the 1/2.5" sensor in the SP-550UZ) but apparently that's not enough to make a significant difference in noise levels. The Stylus 1000 also has the 1/1.8" sensor but based on what Steve's has to say about how noisy the pictures that Olympus gets from the 8mp sensor, it was bad enough with 8mp, squeezing in two more mp into the same size sensor can only make it worse.
Also note that Steve's mentions that "noise levels are higher than normal, even at ISO 64" with the 8mp Olympus 1/1.8" sensor. Yet they're selling PnS cameras with 5000 or even 6400 ISO. It sounds to me like ISO is the new megapixel, according to the marketing folks. Now if only the SENSOR would be the new megapixel... only Fuji seems to actively promote the sensors in their PnS cameras.
How would marketing people justify their big salaries if they focus on the same feature, and it's a valid feature to boot? 
. And you wouldn't want that to happen, right? 
Don't risk it, go out and buy several cameras and get those pictures from different cameras taken!
