Hello all, I was planning to wait till Spring to buy a MacBook Pro with Leopard already installed, but I just came across a deal I cant refuse. I was wondering if I could get an price estimate of how much it would cost to upgrade the current OSX to Leopard at a later time? Would it be a simple software update download with a fee, or do I have to go out and buy the software package at a store? Would the upgrade even be necessary? Thanks in advance for your help!
