Is Sharp even in the running.

TI is superior on educational market since 36X Pro and there are superb features included in these scientific models (eg. differentiation by ANY variable in Classic mode) or SUM() can handle numbers in polar form and many more.

TI-36X Pro is like 83/84 without graphics and one of the best (IMHO the best) scientific model. Other manufacturers can't beat this capability (yet).

I can imagine a (TI?) model with QR and a camera on back to share QR directly from unit-to-unit and/or from monitor-to-unit.

Only a little programmability is required for TIs and they are done.
