Illustrated Blog

I've figured out what this blog needs. Pictures! I finally have a use for a digital camera. Believe it or not I don't own one. (I don't have a Tivo either, but that's another story.) I like the size and shape of the Canon Digital Elph. It's gotta be compatible with the Macintosh so I can upload stuff on the Powerbook, too. Any suggestions? I'd like something that can do 2 megapixels but don't need much more. And I don't want to spend more than I have to.
