The D750 is just a rebadged K750, nothing more

Not likely back then! CCD modules where VERY VERY expensive, and very few manufacturers could make them for use on cellphones.
All digicams, except some of the large dSLRs use CCD sensors. How come these are not "VERY, VERY expensive"?

that's quite incorrect. Many low end digicams use cmos, and even some DSLR's use cmos (which once was unheard of).
Apart from that, a digicam is a dedicated package. The issues of space and energy consumption are not so much of an issue in dedicated cameras because they are not competing with other phone functions for the limited space and energy.
Anyway, if you want to argue that CMOS isn't cheaper than CCD then you are fighting a losing battle. It's pretty much an accepted fact, just google or wiki it. Infact, due to the cheapness and lower power consumption of CMOS, the reverse is happening. Due to more development going into CMOS because of it's advantages in small convergence devices, CMOS is becoming as good as CCD, and one day CCD will cease to exist in all but ultra high end gear.

so agreed; w810 is (in my opinion) best SE phone

it doesn't have an active lense cover which is essential for a camera phone. This is one area W810 loses out because it is a walkman.
W810 has EDGE, screen light sensor, and a brighter screen. These are the only advantages over K750 (and of course the Walkman player). These don't make up for lack of active lens cover in my view.

Do you know of any specific models? I know of only one, the Kodak C513.

I know. My Canon 300D has a
huge CMOS sensor, compared to what you have in camphones (4/3" vs 1/2.8" in K850i). With these large sensors, sensitivity goes up.
Anyway, if you want to argue that CMOS isn't cheaper than CCD then you are fighting a losing battle. It's pretty much an accepted fact, just google or wiki it.

I didn't say that CCD is cheaper than CMOS! I just don't agree with the description of CCD being "VERY, VERY expensive". But I agree that CMOS will
one day overtake CCD in quality and low-light performance, just not yet. The two year old i-mobile 902, which currently sells for about USD 200 on eBay, still beats even the latest offerings from Nokia and Sony Ericsson.

the i902 is an exception to the rule though. It is a large and heavy phone.
CMOS is more likely to remain the sensor of choice for phonecam manufacturers as imho CMOS will increase in performance quicker than CCD will decrease in size.
I take your point that CCD aren't very very much more expensive, though at the time of the S700 they were considerably more expensive than cmos to produce at sizes small enough to fit in a camera phone.
And by low end dedicated digicams I meant el cheapo no-name brands! You are right most Kodak, Nikon etc all use CCD. And until recently the same was true of DSLR. I notice Canon now are using all CMOS for their DSLR's. The quality of CMOS is easier to manage at large chip sizes, but as CMOS improves, they will work their way down to all models.
Camera phones will also help drive the improvement of CMOS technology.

It is
identical in size to the K850i (well actually it's half a millimetre thicker), and about 20 grams lighter.
The
only thing on the 902 being good is the camera module, but that's because this part is produced by Sony. The rest is of fairly poor quality. I don't recommend it unless you want to spend 200 dollars on a phone that may break in six months. Which mine just did

well the cheapness of the rest of the 902 then explains how they could afford to use a CCD instead of CMOS.

It actually didn't
I opened the phone. Loose connection to the "vibrator" caused the phone not to detect battery charge and wouldn't allow charging. Now it's working fine again!
