I recently discovered a good reason to be running Canary/dev channel. Chrome version 22 introduced a bug with heavy JSON pages, where navigating away from them would lock up the browser. Our page had been working great on all browsers, then literally on the morning we went live, Chrome 22 was pushed out to auto-update, which broke this page for our users. If we had of been running Canary, we'd have seen the issue earlier in the development process.
