if you really want to get to low down on the S10 check out
http://www.dpreview.com/reviews/canons10/. Their they compare it with the then "best of the best" (when the review was done) Nikon 800 and it passes with flying colors.
Another feature the S10 boasts that most cameras can't is the ability to zoom in on a picture on the tiny LCD screen, so instead of looking at that 1600x1200 image on a tiny ~2" screen and saying to yourself "yeah i looks great at 2" but when I get it home on my 21" am I gonna notice a slight blur/distortion/pixelation/etc?" you just press the zoom button and you get a much better image, probably comparable to a 6x6" screen. Granted that's still damn small, but trust me it sure beats 2". You can also use the zoom when you're connected to a TV.
I went from a super crappy (well
now i think it's crappy) Polaroid 640x480 camera to this and was amazed at the difference, I figured my Polaroid wasn't so bad till i saw what this could do!!
Check out what
dpreview had to say in the conclusion:
"The Canon S10 certainly sets new ground, and I'm sure it's sent a few manufacturers racing back to the drawing board (as I'm sure the 950 did when it was released). The S10 is just so good on so many grounds it goes high on my favourite digicams list. With the addition of USB, CF Type II, Super-Fine JPEG, its small size and value for money, if you can live with the limited zoom ability then the S10 is one camera that ANYONE considering buying a digicam should have somewhere in their list.. (somewhere near the top).
Kudos Canon, you've produced a digital camera capable of taking beautiful images in anyones hands, with a great feature set and some neat touches it makes some larger bulkier digicams look like dinosaurs and brings compact digital cameras to a new level."
really it's not fair to put the S10 next to those other cameras, the S10 is in a whole other league, like comparing a Pentium 2 with a Pentium 3, it's a whole new level
