The TI-89 is a graphing calculator used in advanced mathematics classes and approved for use on examinations like the Scholastic Aptitude Test and various Advanced Placement tests.

Seriously TI -- it's 2012. The TI-83 Plus has a 96 x 64 resolution LCD. Are you kidding me? You're selling a "graphing" calculator in the year 2012 with about as many pixels as I have fingers?
