Yesterday I was looking for the name of the old Sony mp3 player I had in the early 2000's. It took ages to track down with any certainty: "Sony NW-E105". Like, what does that even mean? I just remembered it's this circular thing and it was purple. I'll never remember that model number and I had to rely on my browser history to even paste it in this comment just now, even though I was just reading about it yesterday! Brutal.
