ok so i went and i was approved for the 10$ snow leopard osx, i went i ordered it and then i put it in and let it sit for an hour while it did its thing. i came back and it said welcome to snow leopard and well now i read that its possible i just upgraded rather than full install, what would be the difference and my MBP is the one from late august, so a newer MBP but i feel i dont have the full SL on it. my version is 10.6.1 so maybe i do but i need some clarification.
