After a very disappointing time with Aperture 2, I am trying beta 2.0 and liking it a great deal. I gather I am taking a chance in being able to migrate libraries worked on in the beta into the release version. My question is whether it is best to buy 1.5 and work there till release? If I continue with beta, what files will I need to remove inorder to be able to reinstall after my 30 days trial? I gather that release date is unkown, right? Thanks
