A playback device for storing and delivering audio and text content to a user. A local computer delivers customized content to the playback device via a wireless signal, such as a wireless local or wide area network. The local computer can receive content using a predesigned profile that downloads content from the Internet at one or more content provider web sites and/or a database. The playback device generally comprises a housing, an LED display, a set of programmable buttons, including a response button, an audio delivery device, such as a speaker or headphone jack, a microphone and a set of inputs and outputs. The electronics of the device include a microprocessor and system bus which couple to a microcontroller and power source, memory (volatile and nonvolatile), display device, an I/O connector, compact flash, and a docking connector. The microprocessor is connected to an MP3 decoder, a codec, and audio delivery devices. A number of possible optional modules can be connected to the playback device, such as a cellular telephone, global positioning device, security or system monitoring device, or the like. The buttons permit a user to power on/off the device, listen, fast forward and reverse, select category, start/stop/pause delivery, and control volume. There is also a response button which, when actuated by the user, enables subsequent processing and upload to the local computer of an instruction for more information or for purchasing an advertised product.
