Statosphere offers quick visual feedback to your Mac\'s vital activities, including CPU and RAM usage, network activity, airport wireless strength, battery level (if applicable) and harddrive space. Users can select which information to show on each of the widget\'s three dials through unique, drag and drop preferences.
There are plenty of other widgets that do this exact same thing for free. I think by charging you're destroying the spirit of the whole thing. Way to go.
