I just got the S30 a few minutes ago.
Chunky/blocky/big. Almost not pocketable. About as bad as our Canon D10 but more square.
Battery compartment covers are odd and very not kid (or even adult) friendly. Don't expect Junior to be replacing the batteries on his own.
I groused over the above and my wife said. Oh she won't care about any of that.... it's pink so she'll love it.
The speed seems ok. The interface is nice but it took me a bit to figure it out. It was not immediately obvious that you hit the menu option you want that is lined up with one of the four menu buttons on the left. I was scratching my head looking for an OK or SET buttons until I figure out that essentially there are four OK buttons.
