I am notifying you that I will no longer support you. You have actively locked down assembly development for the TI-Nspire, and to some extent, the TI-84 Plus Series via 2.53/2.55 MP. I will no longer buy your calculators, nor use them in class. I am the leader of the Union of Concerned Calculator Programmers (http://uccp.ucoz.com) and I will use a Casio Prizm in class as soon as I buy one.
