Does Anyone Still Even Have Audio Cassettes That Need To Be Digitized?S

Hammacher's hawking this over-sized walkman look-alike featuring an iPhone/iPod Touch dock that lets you convert cassette tapes into MP3s via an accompanying app. But does anyone out there even have audio cassettes that can't be more easily replaced with a quick iTunes search? Does anyone even know what audio cassettes are? Besides maybe a reporter with a box of old interviews, who would drop $80 on this? Or is there a demand we're just oblivious to? [Hammacher Schlemmer]
