I have my chartered finanial analyst (CFA) designation and the ti-ba II+ is the only calculator allowed for the 3 years of exams required to get the designation. It is a very simple device and this lock-in is the only way I would have paid $65 for each of the three I own.

There's no reason that you couldn't make a simple open-source web-app calculator that performs all the functions of that calculator.

The TI-BAII+ is primitive in comparison to what is possible to program and create a web-gui.

Heck they have even made their own iPhone/iPad version:

Really? I thought the HP-12C was still the gold standard in finance.

It is, and the HP-12C is allowed for the CFA exams.

That said, it's a very short list of what calculators are allowed.
