I've been seeing Snow Leopard showing up on Amazon for $25. It seems too good to be true. Is it? I'm hoping not because I really need to update (I seem to be quite outdated for a few things) and I can't justify paying regular price on it. Yet, the realist in me is screaming that it's some sort of scam, or there's at least some sort of catch. Anyone know? I have ten days to upgrade and download Steam for Mac and get a free copy of Portal!!! lol EDIT: I am still running Tiger.
