Hi, I'm trying to figure out how I should partition my HD or more specifically how much space I should allocate for both OS's, software, and storage which should bring me up to 4 partitions. I have the new iMac, my first apple product , which has 60G. I would want the storage for the OS and software to be flexible and expandable for my future needs. As of now i have no clue on how much space each operating systems and the softwares currently consume on my HD. Any suggestions?? J.C.
