One or more storage modules in accordance with implementations of the present invention can be configured for a direct physical connection to a portable, digital playback device. The one or more storage modules comprise computer-executable instructions and one or more media files for delivering content directly to the portable playback device. Thus, for example, a potential customer or end user can plug-in a purchased or rented storage module directly into a personal digital playback device and watch movies, listen to music, watch/listen to news programs, or the like without necessarily having to download content through an intermediate computer system or network interface.
