RE: Thinking of acquiring new Sharp (gasp!!) model
The 991EX (not ES) has one feature that I think is brilliant, and I haven't seen it on any other models just yet. If you want to solve an equation (arbitrarily hard; no limit) or graph a function, you can press one button and the calc generates a QR code on the screen. You scan that with your phone or tablet, and it takes you to a web page with the full solution or graph.

I still feel that the 991EX is my favorite non-HP model out there. Truly a workhorse for a non-graphing calc.

For example, taking the example from the Sharp calc display above, the 991EX generates a QR code which then takes you to this page, to view the result:

That was a poor example, but here's a good video on how it works:
