Ahh, the devil is in the details - my Macbook is still running 10.4.11 and I need 10.5 to sync up iPad. Any suggestions on where I can purchase this, perhaps a family pack for my household? I'm having a very hard time finding it. Thanks in advance.
Like Hell-Hammer said, grab a copy of Snow Leopard and 1GB 200-Pin DDR2 SO-DIMM RAM, which comes to a total of $55... or 4GB if your MacBook supports it, it will be worth while.
