Summary: G10 exceeds expectations
Comment: The G10 is an amazing camera. I bought it a week or so ago based on Michael Reichman's (luminouslandscape website) and Thom Hogan's (bythom[...]) reviews. I am an advanced amateur/prosumer -- I sell fine art landscapes, and have been photographing for about 35 years.
The G10 is heavy at about a pound, but I like the heft. It is quite compact (at least from my perspective) -- the lens fully retracts and it will fit in a large jacket pocket. I have a medium-large Zing pouch I put it in and carry in my backpack, or alternatively put the Zing pouch on my belt loop.
I'm astonished at the image quality and functionality offered by the G10. I haven't shot any jpegs, only RAW (using DPP to process RAW; the RAW images will no doubt be more malleable with other software when they support the G10 -- DPP is fairly limited). In RAW, at ISO 80 on a tripod, I think the detail rendered by the G10 exceeds or at least equals the Canon 5D. It may have a weaker or virtually no AA filter.
The lens on the G10 is fantastic. There is very little resolution fall off, even wide open, edge to edge and into the corners.
In my mind, the closest equivalent to the G10 is a Fuji 645 medium format rangefinder (remember the small zoom range Fuji 645 compact?), but the G10 is better in almost every way. The G10 is far lighter and more compact, offers a great zoom range (and is sharp throughout the zoom range) and image stabilization, and has enough resolution to produce fine art quality prints, up to 18" or 24" in the long dimension without stitching.
I think the G10 is opening up a whole new world of landscape, street photography possibilities, and what about the incredible macro versatility?
There is a substantial drop off in image quality from ISO 200 to ISO 400 on the G10, but ISO 400 is still very very good (again shooting RAW), much better than the panasonic LX3 that I tried for a week or two at ISO 400.
I must be crazy. I can't believe a compact with such a small sensor can render detail this well. I'm seeing the G10 as a whole new tool that will open up different possibilities and different ways of seeing (and have different limitations than a Canon DSLR). I haven't been this excited about a photographic tool since I purchased my Canon 5D over 3 years ago.
The Canon G10 offers "automatic" settings that I haven't tried. For an advanced photographer it offers a wealth of manual controls and customization, which I'm still learning. One very nice touch is that the custom settings on the top dial (there are two) allow you to save the zoom settings and manual focus setting -- so I have one saved at a 35mm focal length equivalent and another at a 50mm equivalent. This allows quick, street shooting, similar to what one can do with a Leica rangefinder, though the G10 has a much different look given the virtually infinite depth of field due to the small sensor.

Comment: I bought this camera, waited, got ticked off at the price drop then it arrived. Charged the battery (doesn;t that suck with electronics, you get the thing and then wait till the battery charges 8 hours) I get it, plug it in and turn it on. And let me say, I was laying on my stomach on a bed with the camera facing down. When the camera turned on it was about 2 inches from this throw blanket thing. On the screen I could count every thread with no blur. I said out loud. "Wow.....that;s ****'in ridiculous"
I think went on to use the camera in the last 2 days. I've taken outdoor shots, art gallery photo's, night shots etc. The best thing is, in galleries, flash camera's are not allowed. This thing sucks light from some cosmo's unknown, leaving me with perfect shots and leaving them thinking....You jerk.
The camera starts up in less than a second, it's not big and bulky at all. It cannot fit in your pocket, so don't buy this camera if it's just for you and your friends to post pictures on myspace. (p.s. your lame) buy this camera if you want photo's that capture every imagine perfectly. Has a screen that makes me want to watch movies on (it's a 3" LCD that is simply amazing). I'm taking this to Rome soon. And I know that it will capture the best pictures possible. And then a little gypsie will steal it. And I'll be sad. But when I rebuy another, this will be the one I buy.
