Should I keep my copy of Mac OS X Snow Leopard?
I have recently upgraded to Mac OS X Lion which I am very happy with and have no compatibility issues. I have a retail copy of Mac OS X Snow Leopard and was wondering whether it would be wise to sell it? My understanding is you need Snow Leopard to upgrade to Lion so if I ever have any issues in the future will I still need my copy of Snow Leopard?
Thanks in advance for any help.
