   I have a TI-83 graphing calculator and am thinking about upgrading to the 89 because extra useful features. Is it worth it?

   There have been several discussions regarding the choice of a calculator. I recommend that you do a search on the forums. Also the type of calculator you want depends what you intend to do with it.
