While the TI-83 has the most games of any TI calculator, it is not as prolific with math and science programs, which was exactly why TI made their graphing calculators programmable. I know that games are popular and seem important on a calculator, but they will not help with exams. I have many games on my calculators, and use them often. However, it is math and science programs that are where the real benefits of programming are reaped, as these can easily make or break a grade. So far, I have written two programs for the TI-83, but should be porting some of the programs that I have written for my other calculators soon.
