I have the 83+ silver . It's neat - more memory, faster processor. Draw fast, plays games nicely.
High school it is understandable, but at a univesity level professors "assume" that you know algebra and trig quite well. I've had a 89 ever since freshman year in university and I could use it in every class. So what that you know how to punch in numbers and get the answer, you still have to show your work for credit...an 89 is a great thing for checking your answers though. It helped me most in calc 3 with all the 3d modeling.

An 83 silver is, like many before said, a waste of money. It has some extra things that you could download for an 83+ or an 89. The periodic table of elements has a nice interface though...but it sure as hell is not worth 30 bucks more than the normal black one.

So, in other words, get a freagin 89 if you are in college!
