Query: I love this calc

This calculator is worlds ahead of both the TI-83 and TI-86.For the most part, the calculator is pretty intuitive. After 10 or 15 minutes, you get the hang of it and can pretty much do everything you could do with the other TIs.Of course, that's just the tip of the iceberg. The CAS (computer algebra system) is great. You can take derivatives or integrals of functions of one (or more) variables. If you don't have caluclus, you can factor or expand expressions, which is great for avoiding tedious algebra.If you're into programming, you can find some great resources for programming it in C, or use the BASIC-like language built in to the calculator. With the built-in language, you can create both programs and functions that return values just like built-in functions.I feel that I must address a common complaint. I didn't notice the screen being tilted or at an angle, even upon close inspection.
