Hi A. - before you shop for cameras, let me tell you a couple of things about taking photos. I suspect you old Canon's default setting was "fully automatic". This means that the user (aka you) want the camera to have full control of taking the photo. This also means that the camera needs a few moments to figure out what you're trying to take a picture of and then puts all the information together to take the best picture. This is why there is a two-second delay between when you push the button and when the picture is actually taken. My new Sony does the same thing. The fix is to read the instruction manual and find out what camera setting allows the user to control the moment. In most cases, this is a "P" setting. Another setting that will help you be more instantaneous is to turn off the red-eye flash feature and just go with standard flash. The camera probably has an edit setting that will fix the resulting red-eye.
For your next issue - zoom - the little pocket cameras are going to be generally poor in this category. Because the big idea now is to make the camera as slim as possible, the shell case doesn't accomodate the length that a good zoom lense needs to extend. The type of camera that has the round lense that sticks out from the case is probably going to get you the best zoom, but you'll sacrifice overall size. For the most part, all camera brands compete equally with each other - Canon, Sony, Olympus, Kodak - its just a matter of how much money you want to spend. If you've been using a Canon for 6 years, I'd stick with a new Canon. All the buttons and symbols will be familiar already, and a new camera will be light years superior that the 2004 model. It can even take HD video if you want it to.
