<< 3Mp cameras are not practical in this form factor.
Nobody has succeeded yet in creating this small of optics that can produce 3Mp worth of information.
Read the reviews on dpreview of the Optio 330 and the Kyocera.
The resolutions obtained are only slightly higher than the previous generation canons, and both exhibited considerable other image problems.
I think canon has it right with the digital elph line, try to take the best picture you can within the limitations of 2Mp.
I have printed 8x10's from my S100 that look fantastic.
Do not judge digital cameras by the Mp number alone.

This is true, and a small form-factor 3.34MP digital camera does not have the resolution of a larger-bodied 3.34MP camera, but that still doesn't negate the fact that a tiny 3.34MP digital camera still has better resolution than a tiny 2.1MP digital camera.
Probably most importantly, IMO, is the Optio 330 is higher resolution, has 3x zoom, and is closer to the size of the S110. The S300 just seems so much larger when you compare the two. And then when you look at price, the Optio gives more for the money.
My Optio 330 was $399 after MIR from Photoalley 4-months ago, and that included an extra Li-Ion battery. I haven't shopped around for them lately, but I'm sure they're still price competitive with the S300's. Photoalley is not exactly the cheapest place to buy stuff.
I don't mean to come across like I'm thread-crapping, but just pointing out that a big name brand and popularity doesn't necessarily mean it's the best product for the best price. There are other lesser-known names out there that are a better bang for the buck.
