I never thought that word ´intuitive´ could be applicable to an HP grapher but the 40GS is intuitive - user friendly. And unlike the TI´s, it´s not built like a kids´ toy and the screen is clean and readable.
Most HP graphers assume that you´re an engineer and so you´re smart enough to figure out how to use the calculator without any help. The 50G is an incredibly powerful little machine but it is tough to figure out and there is no good documentation to help unless you want to print out the 800+ page PDF file, which goes into more detail than you´ll ever need. Not so the 40GS - unless you really need all the high end features of the 50g, buy the 40GS for half the price and you´ll be very pleased.
I have used just about every grapher out there - TI83,84,86,89, several HP´s including the 50G. Since I don´t need everything the 50G supports, I decided to try the 40GS after reading some reviews here on Amazon and seeing that it´s reasonably priced, and I am very satisfied - won´t be using anything else from now on. Even programming the 40GS is a snap - you actually have a little IDE for developing programs, and you don´t need to use RPL.
. And summed up by saying FINALLY!. Currently HP 40gs Graphing Calculator (F2225AA) has an overall rating of 8 over 10.
