I have a MBP and I'm wondering what good Time Machine is for me. I'm not the type of user to put my MBP in the same spot everyday and connect an external drive. I'm just wondering if Time Machine is useless for someone like me. BTW, the demonstration is making me really want an iMac. I'm thinking I can put most of my music files on it and then have more space on my MBP for bootcamp. If I can swing that, I can easily sell my Dell Laptop and not miss it too much.
