Congrats and I hope you keep that Zune nicely charged all the time so you don't end up with a Zune that cannot hold a full Green charge once disconnected from the USB like mine. Now a full white charge once disconnect means fully charged for my Zune. Man I kinda of miss that green light, but oh well at least my Zune still works like it should.
It's not supposed to show green once it is disconnected. The green battery only shows up when it's connected to the computer and fully charged.
