If I had Touchpad models, I wouldn't upgrade them to 2.1: it's likely that as usual, documents created with newer OS versions don't work on older OS versions - so besides potentially facing other unpleasant yet-unknown surprises TI might have hidden in 2.1, you'll probably not be able to open documents in the future, should you downgrade to 2.0.x for some reason.

Moreover, the TouchPad and 2.1 protections seems to be different.

On the TouchPads, you can't install OS 1.7 or older, and if you try, you're getting the error at the beginning of the file transfer.

On the 2.1 OS, you can't install OS 1.6 or older, and if you try, you're getting the error at the end of the file transfer.


Installing the 2.1 OS on a TouchPad will give you 2 different downgrade protections.
If one of those protections is cracked, you'll be very sad because you'll still have the other protection.


I think the TouchPad protection is hardware-based, and the 2.1 OS protection is software-based.



We should avoid using the 2.1 OSes, because all created documents will only be readable by 2.1 or higher OSes.
If we share those documents, people will be forced to upgrade in order to read them...
And that's exactly what TI wants!!!

Rooting the calc would allow us to modify the hardware clock rates and give us access to the raw machine. unlike a hack of the TI front end which gives access to run things in user mode.

the touch pad and click pad versions of the nspire are identical I have both keyboards and bought my nspire before the touch pad existed. the only reason you get an error is that the old OS's don't have drivers for the touch pad so they fail. moving to an OS pre 1.7 with the touchpad on the calculator gets an error. doing it with the clickwheel doesn't.

It'll work, but only if you buy a clickpad from ti. The touchpad doesn't work, but a touchpad calc with a clickpad will. Luckily, TI recently reduced their price for keypads to $10. They used to be $40

no, the original cas has no swappable pads. Sorry!

The second gen cas does i think, but it's not compatible with the 84 either, just with itself.

Altough I am not very active right now, I just saw this after returning from work and was very dissapointed by Texas Instruments.

Something I have been wondering, is this legal from them? Are they allowed by human software rights to prevent people from using the OS they want on the handheld they BOUGHT?

They are really going far, now, and IMHO, this deserves to be seen by the rest of the world, not just the community. Because of this, I have decided to submit this to Digg.

Link below:
http://digg.com/software/Texas_Instruments_takes_control_of_their_TI_Nspire_customers

If enough people digg this article, it will show up on Digg front page and more people will see it, then it will get spread among other sites, if they consider this as worthy as the similar crap Apple and Sony has been doing with their products.

Does anyone know the french equivalent of Digg? It should be submitted there too, linking to TI-BANK. I wonder if it would be Slashdot-worthy?

Anyway critor, I am moving this on front page. The 30132 posts in a year record breaking can wait. Thanks a lot for letting us know about this. I am gonna edit your news, adding a third link, to the Digg article.

Please, people, do not upgrade, even those with the Touchpad! What if TI blocked every possible ways to install Ndless on this OS?

It's past midnight here so I don;t have much time but perhaps sending this to the Electronic Frontier or something like that will help?

Nice, DJ. Very necessary, I think. TI has crossed the line.
Wow, I just read about something related earlier today while deciding whether to license a new project as GPLv2 or GPLv3. Specifically tivoization, which refers to putting free software on a device but not allowing a modified version to be put on the device (this refers to TiVo, of course)
I agree that one shouldn't be prevented from using a device as they wish. (This is a reason I don't like cell phones, b/c you can't easily change the OS) I, therefore, am against this move (as is most, if not all, of the calc community) and, despite not owning an Nspire, believe that this is wrong on TI's part.
I'll get off my soapbox. :P
Digg it, fellow forum members!
