I thought that Ndless 2 was going to be for 1.7 and 2.0.  I think I read that they did not have it working right on 2.0 yet and they were waiting to release it until they had it working on that OS.

Ndless 2 hasn't been released yet and might not be for a while. In addition, later versions of the OS might do similarly.
The other reason it's bad is just the conceptual part of it. For example, I object to Apple despite never having owned anything of theirs.
In short, the actual restriction and what our philosophies are.

The problem is actually that you never want to know what else TI hid in the OS.

And seeing as they only added about three math features and they saw fit to release a new version, it is most likely that they were anxious to release it for the anti-development tools.

btw, I think the lock code was already in some of the the previous OS's, (probably 1.7 and up) and is activated with 2.1, so if you downgrade to 1.7, you still can't downgrade to 1.1 even if you have it.

As far as I know, Ndless2 is not stable, neither on the 1.7 OS, nor on the 2.0 OS.
It's juste worse with the 2.0 OS.

Do as you wish... But if I were you, I wouldn't update.
Because I can't tell if Ndless2 will be released in 2010 or 2011, or even if it WILL be released...

that is true.. i just hope my nspire doesn't come pre-shipped with it installed already! :s
edit: just realized something.. reason of not upgrading is to downgrade to os 1.1.. but if the nspire cas with touchpad can't do that anyways, would it make a difference for the touchpad models?

Is TI doing this because of complaints from teachers, or is there another reason?

What if OS 2.1 fixed every possible exploit (there are always holes somewhere, but sometimes, we never know) allowing installing any form of Ndless? Sure, the OS allows downgrading to OS 2.0.1, which, eventually, might have Ndless, but has anyone tested the new OS on the touchpad Nspires? Can they even be downgraded from OS 2.1 like the others did (to OS 1.7 through 2.0)?

Also, seeing this, I wouldn't be surprised if eventually, all next TI OSes prevented downgrading to any older OS, even the very prior release of it. And we never know if such OS could come out soon. What if TI notices bugs in 2.1? (when OS 2.0 came out, Mic Nspire died while doing USB transfer), and TI stuff is not tested well, typically. For that I wouldn't recommend installing this OS on your calc until next release, but since next release might include an even worse downgrade protection, I would recommend the next update even less.

I'm not sure Ndless is that well-known. Correct me if I'm wrong, but it's probably because TI just hates us, as they have demonstrated multiple times, including a lack of documentation for newer models and the recent key-signing controversy.
Our relationship with TI is a love/hate one, or, in other words, that of a hacker. ;D

Btw, I somehow have the feeling Texas Instrument will delete the comment about the impossible downgrade on their Facebook page. I wouldn't be surprised if they did that. In case they do, I have taken a screenshot of it below.

I think we need to slashdot this.

TI is probably doing this on it's own accord.  Even if a teacher complained about it, I don't think TI would care.  If a lot of teachers complained, then maybe, but I don't think a lot of teachers even know about Ndless.

I think that TI sees this as a whole lot of problems.

What I mean is, I remember teachers complaining about the Ti-83+, Ti-84+, etc. being able to hold custom games students could play in class, so I didn't know if TI was trying to prevent it for the Nspire
