They show nice details and are pretty sharp. I take it there weren't a lot of post-processing done. I'm very impressed there is very little noise showing on both pictures. I think I will be buying one tomorrow from Best Buy. Amazon would save me $28.20 in sales tax but God forbid, should I ever encounter Canon's infamous E18 error, I don't think they would accept such return. Best Buy, on the other hand, told me I can swap for a new camera within the 30-day return policy (I don't think their extended warranty will cover lens error; I'm pretty sure I will have to deal with Canon. So it might not be worth spending the extra money for their extended warranty).
Regarding my obsession, yeah, I can't help it. I've been reading a lot of reviews on Canon, Best Buy, Amazon, and other websites, and for every positive comments I read, the negative ones would drive me nuts. Luckily, though, expert reviewers and happy owners on forum sites such as this one, have convinced me it's a superb camera.
Thanks everyone, and I hope to post some pictures down the road. Please try not to get too annoyed if I ask for advice on how to get better pictures with the S100.
