I have a Powerbook G4 and I was wondering if Toast 7 is worth the purchase. I currently use the built-in Disk Copy program. But, I've noticed that it's difficult to write multiple sessions with Disk Copy and in general I think it's very slow at burning. So, I was wondering if Toast 7 is a highly recommended program. What sorts of things will Toast 7 allow me to do that I am not able to do with Disk Copy? Thanks.
