Should I get a TI-89 calculator?

<p>Are there any specific reasons why it wouldn’t be that good for AP Stats? I already asked my AP Calc teacher and she said she thought the TI-89 was awesome, but I haven’t spoken with my AP Stats teacher about it. I’ll ask him even though I’m pretty sure he uses the TI-84. Are there any other comments or suggestions? Thanks a lot to everybody who’s posted ;D</p>
