Almost 11 years later.....TI 89 Titanium have an equation writer similar to HP 49/50g calculators....even an note app, geometry app and spreadsheet app....the old Ti 89Titanium and TI voyage 200 has all this features as downloadable content.....for me TI 89 Titanium is far better bacause has a easier user interface than all the nspire line
