I just checked the tripod mount on my S90, and it looks like it's smack bang in the centre of the lens.
As for the pop-out flash, it's motorised. I don't know if that makes it more os less robust, but there you go.
I've read that the S90 is basically the same as the G11 but with a different body and lens, which gives me hope that CHDK will be available for the S90 soon, since it already is for the G11. It does shoot RAW out of the box, though. You won't need CHDK for that.
Hundreds of years before the dawn of history
Lived a strange race of people... the Druids
No one knows who they were or what they were doing
But their legacy remains
Hewn into the living rock... Of Stonehenge
the vast majority of us want to be able to throw up the latest episode of family guy
Just like Seth MacFarlane does every week!
(kidding, I love the show)
Largest organ of the body...
<the dude>On you, maybe.</the dude>
Bah, this has been the common gripe since the beginning of time.
