Hard to believe, last week marked the 30th anniversary of the Sony Walkman, the original portable music device. Of course, we've come so far since then, what with the advent of iPods and the ability to carry hours and hours of music around at any one time. What would a modern tweener - indeed, sort of like my niece - make of such a dinosaur piece of technology. The BBC decided to find out, handing a vintage Walkman over to a 13-year old to use for a week. He wasn't completely repulsed!
