The Bean is a high-performance pointing stick, providing a precise and complete cursor experience in a small, convenient package.

NOTE: Despite the lack of wires in any of the photos, this is a wired device.

That doesn’t look very usable in the real world.

Sick design though!

I think the nub is in the wrong place. When i was a kid i had this ( https://webassets.lqdt1.com/assets/photos/16167/16167_2131_1... ) mouse from ibm (at the time maker of thinkpads) and that’s a more sensible choice in my opinion.
