I think it's called SD950 in the US.
It's the Titanium one, with 12 MP.
It's the best.
It fits into your pocket, is solid like a brick, not sensetive to scratches like some other Powershots, the Viewfinder is in the right place, you can squeeze it into your eye's corner and hold it steady that way and look through the viewfinder.
The lens is superb, you get the typical Canon Jpeg-smooth-look. I tested it first in a shop because those 12MP scared me, but surprise surprise, even ISO 1600 is useable as long as you use it in not too bad light conditions to get shorter shutter speeds. It's better than the 6MP of the older SD700/Ixus 800 which I owned before. Should be the same sensor and processor as in the G9.
It starts with 35mm focal length, that's boring, but the results are better than from the Ixus 860 (the one with the 28mm), and I prefer the better Jpegs as post-process nearly all my pictures, and the crippled but very well-placed viewfinder.
And boy, it's fast. Really fast.
Well, it's the most expensive .... More expensive than the A650.... for whatever reason...
