By using an older piece of tech that does one thing, you make doing that thing an activity again. As in, it’s a conscious involvement to do that thing now, it’s not just an app or a side feature of some other device.

For instance, I got an iPod Nano a little while ago and just loaded it with the few hundred songs I care to listen to. I use a fraction of the space of the thing if I care to add more music, but now when I want to listen to music I have to use a specific device to do so. It makes it more of a conscious decision to listen to music and, to me, makes me enjoy it more.
