Summary: To Whom it may concern: I have never owned an HP 40GS calculator. I have purchase a cover for an HP 48GX Graphing Calculator. I do own an HP 48GX Graphing Calculator. I used it when I was in school. I loved my HP and took great care of it. This calculator is one of the best for using any and all math functions, and also writing programs to use math. The part I like most is that I could write a short program in calculus using my HP and come up with an answer very quickly.
Bought this for an 8th grader. My 49G was too complicated for her grade level.

Summary: Have only tried out several of the built in functions but seems to be geared for learning as well as to be used as a tool. Bought because I like HP and did not want the RPN (which I prefer) for my daughter. Will be good even if she is ultimately required to buy the TI equivalent.
Fantastic non-RPN HP calculator with the full HP 50g CAS

Summary: This calculator is exactly what I wanted and needed. I have owned top of the line graphing calculators from HP, Casio, Sharp, TI, etc., but overall I like this one the best due primarily to its simplicity and ease of use. I like it especially for trips and outside activities when I can do quite useful mathematical explorations that I don't normally have time for at home or in the office with my busy schedule.
Summary: Everybody knows the Hp calculators are a high level instruments, and of course not to much people use it completely, so intend to discover all the functions its very hard, but in a simple way, the body is solid, the keys are good finish and easy read, the mode to typing is convectional to HP device, in conclusion really good deal,
Summary: I got this calculator at a GREAT price. I am used to using a TI, so I'm still not incredibly familiar with the HP, but it has done everything I needed it to do, and it's definitely worth the lower price.
Summary: Both of my sons were required to have this calculator for their advanced math classes. My older son's stopped working properly at the end of the first school year. We took it back to the store and they were unable to fix it. We went on line to trouble shoot but nothing worked. We had to buy another one for final exams. The following year we purchased this required calculator for my younger son.
