Graphing Calculators

Which graphing calculator do you pick when your son or daughter needs one for school?

I wanted the one that had the most abilty to draw my son's interest in math.  So, after some research I went for the Casio fx GC10.

Sure, HPs are industry standard, but they appear to have quirky syntax. I figured my son can always pick up HP syntax later, if he truly gets interested by using a friendly calcualator early on in his school careers.
Watch for posts that will explain how the Casio fx GC10 works, and helpful features.

• Good Introduction (and great You Tube channel dedicated to the GC10 !)
