How much memory do you think garageband will use up? I am curious how much memory it will take up to write layered songs. I also hope it proves to be a useful program. One of the biggest motivators for me to get the iPad 2 soon (after selling my iPad weeks ago) is for garageband because it could be a useful tool for a number of reasons. I love the idea to be able to flesh out demos right on my iPad. I used to use Multitrack Daw, but Garageband sounds like a step up with the addition of instruments on the program.
