One thing that graphing calculators are really useful for is simple number crunching. In academic settings you frequently need to take down numbers and then compute statistics about them. Tables and matrices are probably the 2 most useful things you can do with a graphing calculator (they're also among the least well known, at least among students). Granted, spreadsheets do all of that and more, but it can sometimes be quicker to punch it all into a calculator, especially if you're already using one.
