Even the most “incredible” or “powerful” or “beautiful” device “ever” will someday go into the trash. The discontinuation of the iPod Classic is a reminder: It doesn’t matter how many oohs and ahhs an Apple product earns onstage or how long the lines are at its launch or how many thousands of dollars impatient rich people dole out for it on eBay. Like a common can of tuna, it has a shelf life, and will someday be worth nothing. But even after its functional death, an old gizmo can still stir something within us. Perhaps it’s nostalgia for a time when phones were smaller and watches were watches.
