I went into a camera shop to "play" with some cameras as you suggested. Well worth it - DH's Kodak is indeed a brick!
I was blown away by how small the Ixus was. They didn't have a 30, but had a 40 in stock. Looked fab. BUT, the sales guy said he didn't think it was worth the money. He reckoned the photos would be comparable to any other 3MP camera. He felt you were paying for the sleek image. Recommended a few cheaper cameras - Fuji, Samsung, Canon A75 (which was quite heavy).
So... what's so amazing about the IXUS? I looked on Which? and they rate Canon above average as a brand. Along with Sony, I think. Kodak et al were average according to them. Which also said the flash on the IXUS was only OK. How do you find it?
Sorry for all the questions. You do seem like a bit of an expert though
