Not quite: people never stopped collecting calculators.

There’s a difference between this and the Casio though. It’s a pretty, limited edition display piece. These are genuinely useful computation devices, for people who like using physical keys to solve problems more complex than a basic calculator could handle. There probably aren’t that many cases where someone needs to use a physical HP calculator anymore, yet some people just enjoy using them anyway.

The kinds of people who’d want to use a re-issued HP probably wouldn’t be too interested in that Casio, and vice versa.
