USB Cassette Deck
Cassette decks are just about equitable to the stone ages, especially with the immersion of high def DVD. The Plusdeck-EX converts your favorite analog cassette tapes to MP3 via USB. It can also handle records, radio and more all thanks to its USB sound card, which also allows you to configure the audio up to 7.1 channels. Not exactly an advance in audio engineering, but a nice option for those analog audio dinosaurs.
Available here for $260.
