I think that compared to a 9 year old camera, most new cameras now are going to be a lot quicker. I have a Powershot S3IS (I think) that I use when it's not practical to take my DSLR, and even though it is about 3 years old, it doesn't really have any shutter lag. Just make sure you read reviews, and stay away from the ones that are slow, it will say in the review.
My dad has a Canon Ixus, not sure what model, but it's a few years old, and I really like that too. It's quite small, so it's easy to carry around, and it's quick.
And even though I am a Nikon girl when it comes to DSLR's, I much prefer the Canon point and shoot cameras.
