I guess Iīm just too old and not sufficiently interested to put in the time but I canīt get my head around my MacBook OS etc.after 20 odd years of windows so I am thinking of using the OS-X for the audio side of things, Itunes and reading web mail and forums with Safari and then partitioning the HD for windows for the rest of my Office programmes and Word documents etc. I know I will waste/lose a lot of space, having to accomodate 2 OSs but I store my music on an external drive and I donīt need all that much anyway. My Macbook has a 160Gb drive - how do you suggest I split it, always giving top priority to audio ?
