If anyone's interested, I've made some observations on the s90 and G11 (and also the Sony R1 since I have one).

s90 Pros
- The G11's control dials are hard to turn with one finger. This makes it a little slower to do exposure compensations and ISO changes. I think the s90's wheel is much faster even though it's multitasking.
- The s90's lens may be as much as a stop and 1/3 brighter than the G11's. Today, while toying with both of them, I noticed that the G11 wanted 1 and 1/3 slower shutter speed for the same exposure.
- I like how the front control ring can be used to step through the major focal lengths. This is superior to the zoom rocker on the G11.
- So far, I just generally find the s90 more intuitive to use.
- Fits in your pocket! This is truly the greatest camera to ever fit in a pocket.

G11 Pros
- The optical viewfinder on the G11 is great (as long as your OK with it being a cropped view). You can shoot somewhat DSLR style, but you can't see what your focusing on.
- It's fun walking around with this camera around your neck and taking pictures through the OVF. It makes you feel more like a photographer to be able to do that.
- The LCD screen comes in handy, although I wish it were a bit looser feeling.
- I do believe the image stabilization is better, but I'm not 100% sure.
- It gets closer macros than the s90. The s90 doesn't focus very close.
- I like that the G11 has dedicated knobs to EV and ISO, but I guess I'd rather have programmable dials for different modes. Also, these knobs pretty much require two fingers to change so it's it's hard to ride them while you're taking pictures.
- The lens might be a tad sharper.
- Doesn't feel as fragile as the s90.

Both cameras Pros:

- Beautiful colors, skin tones, excellent noise reduction. Just very pleasing IQ, even at high ISOs.
- Both cameras offer basically the same IQ with different bodies for different shooting situations.
- I just want to stress that it is amazing that you can get such good looking pictures out of such a small camera (s90). The manual controls and IQ and low noise just makes this thing amazing. They're both good enough that I'll be very reluctant to get out my DSLR in most situations. That's saying alot because my LX3 was my "last resort" and found myself using the D700 more and more when I had it.
- Huge DOF which I desire for many pictures. I don't want all my pictures to have bokeh.

Both cameras Cons:

- When you shoot above ISO 200, you're going to start to loose fine details due to noise reduction. However, if you're printing snapshots like me or viewing them full screen on your computer, you can't tell. I've got ISO 800 and 1600 prints from Walmart and they are just beautiful.
- Facial recognition is a little annoying. It doesn't always pick up on faces as fast as you want it to and sometimes it looses them when you're ready to take the picture. If you're using the facial recognition, you need to press the shutter halfway as soon as it finds the face so you can just snap when it's time to take the pic.
- Both cameras could be faster and focusing and lag, ect. And that brings us to my Sony R1

How my four year old Sony R1 compares to these new Canons

- My Sony R1 is much, much faster focusing than either of these cameras.
- Due to it's larger sensor, it retains much more detail at all ISO levels and far, far less noise up until ISO 1600 when there's basically no in camera noise reduction. The R1 does beat the Canons in low light image quality, as it should since it's a large sensor camera.
- It's got a superior autofocus mode that lets you choose a *large* area in the center of the frame and it will focus on what's closest. It gets it right 99% of the time. I don't even have to look.
- It's got a mechanical zoom like an SLR
- It has dedicated buttons for almost everything that hardly ever get switched by themselves.
- Due to the deep, deep grip, you can't drop the thing. I've never dropped it in four years.
- Zebras! You get zebra stripes like professional video cameras than show you live where you are blowing out highlights. Very, very useful for exposure.
- Like a video camera, the Sony R1 shows you *exactly* the exposure that will be recorded. I like this. I think digital cameras should work like video cameras in this regard.

How Sony R1 is worse

- White balance controls not nearly as good
- It's large with a long lens that makes it weird to wear with a strap
- Although it has DSLR-like images, the color and contrast is not as appealing to me as Canon's.
- LCD is too small and course for anything but composition IMO.

Why did I write this? I don't know. I was just sitting here thinking about it and thought I might share. I also find it interesting that the R1 is still relevant four years later and I'm glad I still have it for certain situations.
