Submission + - Texas Instruments takes control of TI-Nspire users

DJ Omnimaga writes: Since Ndless, a tool allowing 3rd-party softwares to be ran on the TI-Nspire, has been released on ticalc.org (link: http://www.ticalc.org/archives/news/articles/14/145/145908.html ), Texas Instruments has done everything to prevent users from using it. TI trapped the newest OS (version 2.1) that permanently block the handheld from downgrades to OS 1.6 or older. Ndless requires OS 1.1, meaning that once the user upgrades his TI-Nspire to the new OS, he will never be able to use Ndless again on his machine. Is TI going the way Apple and Sony did?

Without Ndless, it is impossible to run ARM9 assembly language applications on the TI-Nspire series of handhelds. Only simple softwares may be written, programmed in the very slow and limited TI-BASIC language available on the Operating System.

More information about the anti-downgrade protection can be found at http://www.omnimaga.org/index.php?topic=3761 . The original article, in French, was posted at http://ti.bank.free.fr/index.php?mod=news&ac=commentaires&id=837 .
