It required the (still) shitty iTunes software, locked you into proprietary hardware, and had limited audio playback features in comparison to its competitors (lack of on-the-fly play queues). A music player it was, but I could (and still can't) take advantage of its storage for whatever else I wanted not could I take it other people's homes and use it to share stuff.

None of those are trivial points.
