Today Fedex delivered my brand new (ok, refurbed) MBP, along with a Leopard upgrade disk. When I get home later to open and unpack the box, should I just plug the MBP in, hit the power switch AND: 1. Immediately install Leopard? If so, what method would you recommend? 2. Setup the machine using Tiger, setting up wireless connectivity etc.--and then install Leopard in a few days? 3. Leave the Leopard upgrade disk in the envelope until Apple releases updates to enhance OS stability, and just enjoy Tiger for a while? Thanks & sorry if this has been asked about a hundred times.
