What the iPod Doesn't DoAn iPod doesn't choose the next song based on what keeps you listening longest. Activities of Daily ThinkingA few months ago I proposed a conceptual framework called Activities of Daily Thinking (ADTs) that was borrowed directly from the clinical language of Activities of Daily Living (ADLs). The iPod trend looks to me like ADT showing up as behavior, not just market adoption. None of them describe what happens inside the person who keeps handing off the small daily acts of thinking and deciding. I don't know if the iPod people would put it this way.
