Hi everyone, need some quick advice here... I am picking up my 13" Macbook Pro today, along with 4GB of RAM and a 320GB WD Scorpio. My question is...should I wait for Snow Leopard before I upgrade the HD (Clean Install), or just install Leopard on the new HD and do an upgrade to Snow Leopard. I have always prefered to do a clean install, but I don't necessarily feel like waiting to put the new HD in either. Any thoughts?
