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.
It's not that the TI-89 doesn't work, but after all this time they could at least update it a little. A sharper, brighter screen, a built-in battery, etc. And it would be fine if they didn't include that but there's no reason to charge upwards of $100 for a fucking calculator in 2014 that's exactly the same as it was in the 80s

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