Not everyone works in finance and/or is familiar with Bloomberg terminals (like me). I think this is pretty interesting since Bloomberg, unlike most application developers, has taken their UX to the point where they're building application-specific hardware (though I understand a lot of that is basically legacy inertia).
Also, programmers seem to be far more interested in keyboards as a subject that most people.
I also thought the B-unit is interesting, it's different than any other authentication device I've used.

They worry about keyboards because it's one of the professions where RSI is common.

I'm surprised, like many other commenters on this thread, that there isn't a more ergonomic version of this, and that there doesn't appear to be an option for better keyswitches, like Cherry MXes. The world of Bloomberg terminals is totally foreign to me, and that makes them interesting.
On a side note, hated my B-unit, always took 5+ lengthy swipes to register.
