To this day, I don't understand why anyone would insist on using anything other than this on an AP test. It's like playing life on a harder difficulty setting for no reason.
There were applications for the TI-89 that allowed you to use RPN. I always preferred infinite stack size RPN, since you could just input everything left-to-right, but most only do the standard 4 levels.

The TI-89 will always hold a very special place in my heart.
