I think one of the reasons why many teachers prefer the old ti83 it is because it isn't online. They don't want people cheating. Some classes you could only have a basic scientific calculator. In a lot of my college classes they just didn't let you use a graphing calculator since you could put a notes in there. Some classes just banned calculators. I just have a hard time believe schools and teachers will allow interned connected devices on tests.
