PI 83 - iPad App Review

I think I may have found my graphing calculator for next year!  It is the PI 83 (much like the TI-83).  And it's only $0.99!!

Features that I like:
~ Can change the size of the calculator by simply tapping on the 1x or 2x on the bottom right of the screen.

~ Can view the calculator in CALC mode or Y= mode

~ Can change the keypad by tapping menu at the bottom of the screen
     ABC (shows keyboard),
     MATH (use this to find things such GCD, LCM, absolute values, square roots),
     PROB (some functions will be useful in the middle school classroom, others more so at the high school level),
     TRIG (all trig functions)
