What are the implications for the software world if APIs are deemed copyrightable in this Oracle/Google case?

I can't see how this could be a good thing for any developer...and I can see how this is a major unnecessary roadblock for many...

But I'm a layman...so hopefully someone with more knowledge can teach me something.

I see Apple fanboys damn near in tears of joy over this yet I can't help but feel like it would be a bad thing for them too, in the end.
