Does a lot of good mathematics, calculations, graphing, and symbolic. However, the interface is cumbersome, too much switching between keyboards and searching for functions. I find it a bit of a pain in the butt to use.

Crash crash crash will editing... Had some luck but basically a piece of crap get the free version paying for it you no advantage

Has a bunch of the functionality of a TI-98 but not all. Lacks a lot of the statistics functionality. Graphs are prettier than a TI which is nice. For the price it is a decent alternative for a good calculator but I'd rather have the calculator easier to navigate. This is more geared to calculus than anything else.

To small to write. Can't zoom in for detail work. I wish it a text option to write names or positions. Even if I was free it would be worth having. I do like that it looks like the clip board we use. But basically my fingers aren't fine enough to make the drawing legible.

Makes a good remote but if want to actually watch something be ready for the signal to drop out every 2 or 3 minutes.
