I've seen Sharp's EL-W516X, Casio's fx-115es and TI's own TI-36x Pro give the user interface which allows for direct equation entry just like HP-48 and 50's Equation Writer. BUT, after I spent a half hour at Office Max fiddling with a TI-89 Titanium to utter frustration & disappointment, I wonder if TI's N-Spire (or any other TIs for that matter) have the Equation Writer functionality that the TI-36x Pro, HP-48, HP-50G, Sharp EL-W516X and Casio fx-115es have?

Please let me know.

Thanks

There is one for the TI-89 but it is not bulit-in. http://www.technicalc.org/packages/eqw/eqw.htm
