Do you ever use a site-specific browser?

My guess is that most folks have never heard of a site-specific browser, but they’re pretty useful things.  If you use web services like web-mail, or a web-based calendars, or any other software-as-a-service tools, you may have been frustrated by the accouterments of a full-blown browser, which can sometimes be a distraction.  A site-specific browser helps in this regard, allowing you to set an icon on your desktop to run a calendar, a content management tool, Google docs, or any other web service.  I’ve used Prism for a while to keep my Google Calendar separate from my browser, which is usually overflowing with open tabs.  And I’ve started playing around with Bubbles lately as well.  It can be a nice productivity tool.
