Use iTunes anywhere without installing anything

iTunes is the Apple program for managing, organizing and playing files and playlists from your multimedia library (music, movies, podcasts, etc.). iTunes also includes access to the iTunes Store, the store for Apple apps and content.

iTunes Portable allows you to use iTunes on any PC without having to install anything: take it with you on a USB flash drive and run it wherever you like.

Keep in mind that this portable version corresponds to an older version—10.6—and not the most recent (11.0).
