So what functionalities would you want from the other emulators?
Well as we have already seen, the fx8200 AU, TI-30XB MultiView and TI-30X Plus MathPrint won't do cos(72
o) whereas the classpad app does:
The TI-Nspire CX II-T emulator also does it:
One thing I like in TI-Nspire CX II-T which is better than classpad is that it automatically closes parentheses whereas the classpad doesn't.
But the other emulators can do other things too not on the fx8200 AU such as
fx570/991CW can do matrices, spreadsheets (not the same as tables), equations, inequalty, Base-N, Ratio, Math Box
The Home screen actually scrolls like this:
It can do calculus too, however the new models hide this in Calculate ->CATALOG ->Fuct Analysis->Derivative or Integration whereas the older style calculators have a simple button. This is one instance where I much prefer the old-style CASIO calculator keyboard - and it appears that CASIO are quite well aware of this because although almost all the current emulators have the new-style keyboard, they kept one in the old-style, namely the fx-570/991EX which looks like this and you can see how much easier it is to access calculus with button
