I have switched almost all my site design to using WordPress. Almost none of the sites I've created are for blogs, and most are set up for use by my clients as a CMS.
WordPress is so flexible, and with all the great plugins I can make it do almost anything.
Just in case anyone is interested, here is my portfolio page: http://kappaluppa.com/portfolio/. You'll recognize some of the templates and some are my own design. My website is my own design using all css and WordPress on the back end. Nothing is hard coded in, everything is a post or a page or an include.
