Good to know. Mine's a 2006 MBP. :( Stuck on something so ancient I don't even want to pull it out and fire it up to figure it out. It's too bad when a $300 netbook from the same year has outlasted my very expensive laptop in utility.
I hope my current rMBP gets a better life expectancy.
I would think you could update that laptop to at least Lion if you wanted. I know a couple people who are still using Snow Leopard just fine since it was solid and fast. The only major app I know of that they've had issues with is the newest version of Lightroom 5 requires Lion.
