I've just bought a new PowerBook G4 with Superdrive, and I'm debating whether or not to buy Roxio Toast 7. I do love what you can do with divx files, and I would like to be able to backup more easily, but since I'm a student I don't have much money to spend. The question for me is, do I really need burning software? I had a very old copy of toast when I bought an external cd-burner for my iMac, and a copy of Nero came with my Windows computer, but I've never actually bought burning software. With added functionality with burning through the finder, is it even necessary?
