Summary: This calculator is supposed to be new. I received it for a present. It came in a bubble wrap bag instead of an HP box. No manual. No warranty card. It is probably "B" stock or used. Very dissappointing.
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.
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.
Summary: The hp 40gs is a strikingly beautiful calculator with a charming underlying precept. However, the idea is still a work in progress. I might not even mention it if there weren't a superior alternative available right now at a lower price (the hp 48gii).
