I'm also inclined to hope that this analysis by The Daily Kos is right and the court's decision basically amounts to "OK, you have to call it 'mawwidge' instead of 'marriage' but otherwise it's exacty the same thing." (I don't know enough to understand if that's correct. But if so it's pretty cunning.)
And I do think that by leaving the marriage rights of the 18,000 already-married same sex couples in place, they're pointing out that California is in a completely untenable position with regard to same-sex marriage.
I know full well that this will lead to at least two ballot initiatives in the near future, and I'm dreading having to go down that road again.
But since we have to go down that road again, at least the pro-marriage side appears to be better-organized now than it was during the prop 8 campaign.
If I were legally married to the OH, I would talk to him about getting a divorce in response to the court's decision. But we never did tell the government.
(However, an unmarried opposite-sex couple has more privilege than an unmarried same-sex couple, because people presume we're married unless we explicitly tell them otherwise.)
Incidentally, because it seems important to be out these days: I'm bisexual and polyamorous.
