Just letting everyone know mine came with SL. I get the consensus around here is that everything ships with Lion. I pretty much read up on it, prepared myself for the plethora of errors and whatnot and lo and be hold, I turn it on, restore from my TM backup, and I have SL on 10.6.7. I also have 2 SL disks that came with the machine. So yea guys, if you really want SL or don't want to get a machine with Lion pre-installed, ask them in store if they have any older models.
