It's nice letting the throttle hand experience what the left hand has been able to do at highway speeds and miles for all these years.
I never liked cruse control in my cars before. But since I got the Goldwing with CC, like you pointed out, I love having the right hand free to rest my grip. After a long days ride, it was difficult to make a grip sometimes.
As to what to do with it? Freak out the other riders by waving with your right hand when you greet them as you pass.
