Canvas is an incredibly flexible theme - it can take a while to wrap your head around everything it can do if you're new to WP.
I use it for almost all of my own sites as well as client sites.
I wrote a post a while back about the different options with Canvas

HiFiSocialWeb is also built with Canvas - there are quite a few design examples and different feature options to give you some ideas for working with Canvas.
Great product and great support too.
