Meh, I consider disc swapping and auto-sync two different things.
For the most part, I don't consider disc-swapping a problem, though I am annoyed with the Netflix thing but that's only because it's every time I want to use Netflix and I already have it somewhere else where I don't have to use a disc at all. It doesn't bother me much on a game because it's every 10+ hours I have to switch a disc.
I guess I could compare syncing to the Netflix disc swapping since every time I want to see my trophies somewhere else I have to resync.
And that's good to know the playFire cards aren't updating, I was going crazy as to why mine wasn't updating.
