Can any TI calc Equation Edit??!!

[Manolo Sobrino]

Last expensive calculator I bought was a black HW4 TI 89 Titanium. I don't really like the screen, but it's definitely much faster than my old regular ones so I have mixed feelings about it. I could have got a shiny Nspire CX CAS for about that price, but I still prefer the 89's. It's just faster to go around and I don't want to recharge more batteries. Besides, Diff Eq. from Lars Frederiksen is enough reason to own one.

I never missed the equation writer (though I tried EQW and it was OK), but I suppose that if you got used to it you might feel like you do.
