I appreciate the quality of the engineering and design, and that the hardware is open to being tinkered with by means of firmware update. The price seems fair for what is offered, and the device looks like it would be very useful for anyone who doesn't have any computer at hand or readily available. Kudos to the project team!

But it's unlikely that I buy one because (1) I tend to be close to computers most of the time, (2) my favorite "HP calculator" is the HP9000/715 due to its sizeable HIL keyboard, its 21" CRT color screen, and its support for HP-UX, pun intended; and (3) most of the mathematics I need beyond paper, pen and blackboard can best be done in a Python Jupyter Notebook (statistics) or Mathematica (symbolic derivations).
