hello guys (and girls), I'm a long time mac user, I'm a musician and voice over actor and I recently (yesterday) purchased a 2011 MBA 11" from a fellow forumite fro, the marketplace (nice guy, and smooth transaction. Haven't gotten the machine yet, but I feel it's a straight up, good deal). it's a 128gb/i5/4gb ram machine and I need some directions on somethings from you guys: 1) 128gb is not enough space, so I'm going to buy a small external drive to have my music library, iphoto library and running some heavy programs like Logic. Which one you guys recommend that's less than 100 bucks? 2) I want to create a partition and have one side as pure storage and the other one install iphoto and Logic. HOW to do this last one? thank you guys, really appreciate this.
