Easy to use (windows-click invocation), usually it shows to you the definition or translation most useful in first place. It switches between definition or translation, depending on the context you are. Playing with the activation/deactivation and order of the dictionaries, then you can adapt the answers of dixio to your needs. I installed it some weeks ago and it has became a standard in my desktop. The recently added features as access to google images, google definitions and the google's text translator made it even more useful to me.
Pros: Easy to use, very complemntary functions, new functions are being added
