Summary: I needed it for a higher math class, but it doesn't have all the functions you need in a graphing calculator. So now I have a very expensive desktop calculator. This calculator will not perform matrix computations.
Summary: This is a very limited calc. It dosen't have many functions nor programs. If you want to get a easy simple calc for like algebra this is good but if your in trig or calculus get a TI not this.
Summary: I purchased mine for $49. Its suitable for any classes through college algebra. For trig you'll want to upgrade as it doesn't graph polar coordinates though it does convert rectangular to polar and back. If you needed to you could program it to input the (x,y) into a parametric graph and so display the results. While my class mates were worrying about how to get their TI's to work I was working on the problems.
Summary: This calculator has many good features. Large enough for keys to be easily used, but fits in a shirt pocket. Uses two cheap AAA bstteries with a button battery for memory backup. It has a detailed instruction book, But the MEMORY is next to IMPOSSIBLE to access. The calculator does not even use the word memory, but uses the word list.
