Presumably the board hopes he identifies/designates the successor to pursue a new golden age for TI.
The $150 you pay for a College Board certified calculator goes entirely towards the ability to use it on a College Board test without being considered a cheater.
If you want to lower that cost, there's always the self-service approach -- produce $50 Android phones with calculator software preinstalled and the phone and wifi connectivity ripped out. Then get the College Board to certify your calculator. You can have TI's market share, if you can get the certification.
