In a growning and disconcerting trend among hardware manufacturers, TI has released a new version of it’s OS for the TI-Nspire series, that blocks off a whole load of its’ user base from using the machine the way they want to.

I guess Apple, Android, TI, et al are afraid that the community will program something so awesome for their hardware that they’ll never upgrade again?

Nspire 2.1 out, don’t install it!.
