The article makes a very astute point: that people are attracted to the physicality, the tangibility of "analog" things. Whether out of nostalgia (because we've been there) or retro fascination (when we haven't lived it firsthand), we can develop an emotional connection with a single physical objects that succinctly and permanently hold an abstract concept in a physical package -- like a letter, a book, a music record, or a photograph.
In the digital world so much of what we produce, consume, and interact with has no physical manifestation what we can strongly identify with. The computer is an abstract filing cabinet which can display what you're looking for on its own screen, or plays abstract 'music files', or streams 'video' from subscription apps. We're essentially asking the computer to recall these things from its "memory", and luckily, they remember with exact accuracy much more than a human would. While we can experience these things, we can't hold them in our hand; we can't share them in a self-contained, self-describing form (like handing someone a book) -- if we can share them at all.
