Just wanted to let you guys know that I just purchased the S100. Been watching for it to be available... and was about to give up hope of it being available for a trip i'm taking in a few weeks.... especially since it has disappeared from Amazon's website the last few days and I've heard nothing of this being released soon. But earlier today i came across a thread on another site, mentioning that some Best Buy stores had them (not on the site, but if you went to the store). Called the local store in San Diego (Mission Valley), and the lady on the phone checked, and said they were out, but that a nearby store (Mira Mesa) had 4. So I vaulted up there, and sure enough they did. Nothing on display, so you have to ask about em. So It'd be worth a call or trip to your local store to check.
P.S. I haven't used it yet... as I am quite shocked that it does not come with a SD card of any size whatsoever, and i got nothing lying around to throw in, and will have to go to Fry's in the morning to get one. But I plan to shoot a bunch of photos tomorrow, and if anyone wants anything checked out, let me know.
