This Friday I am going to treat myself to a new MBP with the arrival of Snow Leopard. Are there any tips or pitfalls to be aware of when transferring data from old MB to new MBP? I plan on using Migration Assistant with firewire. SEEMS pretty straight forward. Need to transfer all applications and data. I still haven't entirely shaken my Windows past, so I am a bit nervous. Also, after the transfer is complete, what is the best/most secure way to wipe out the MB HD, reinstall OSX 10.5, and prepare for an ebay sale?
