When the first iPad was released, I bought the 32GB version and after a while, I thought that it would have been better to buy the 16GB model, because I mainly used it for browsing or using apps, but not for putting movies on it. And I don't need to have all my songs on it. Anyway, now I'm thinking about buying the 16GB iPad 2, but I wonder. Does GarageBand takes a lot of space when you use it a lot and compose many projects with it? I wonder if GarageBand creates sort of an mp3 file for each song you compose or does it play it live with kind of text files, if you see what I mean. Anyone?
