There are worse monopolies, I guess. The 83+/84+ has good software and is neigh indestructible. The physical interface is very good and beats a touch screen. A TI calculator fast enough to run NumPy to build simulations and interactive gizmos would be super cool though. Allowing students to build colorful mathematical animations and physics simulations using simple building blocks would be awesome. Of course that can all be done with laptops but having things in the palm of your hand shouldn't be underestimated.
