The present invention can include electronic devices having variable input/output interfaces that can allow a user to interact with the devices with greater efficiency and in a more ergonomic manner. An electronic device of the present invention can display icons associated with user-programmable parameters of a media file. By interacting with the icons, a user can change the user-programmable parameters during playback of the media file. Changes to the user-programmable parameters can affect playback of the remainder of the media file. An electronic device of the present invention also can automatically re-orient images shown on a display and re-configure user input components based on the orientation of the electronic device.
