In that case, why do people buy the CAS then? :P
Because it's pretty hard to install a non-intended OS. ;)

If you bought both of them, I'M sure it would be legal. Once you paid for both, you should be allowed to do what you desire with them. If you pirate Mac OS on TPB then install a copy on your PC, then it's illegal.

The issue when installing the CAS on the non-CAS models is that when you buy a TI-Nspire, you mostly pay for the CAS/Non-CAS software, not just the calc itself. By installing the CAS software for free on a non-CAS calc, you're stealing $50 from TI.
Installing the CAS OS on a non-CAS Nspire is legal even if you haven't bought an Nspire CAS. The software is available for free on TI's website, and the license allows you to store one copy on a calc and one copy on a computer for backup purposes. It doesn't say anything about which calcs you can put the OS on, so you can install it on whichever one you want to (even a Casio calc, but that wouldn't work :P). If it's ethical to do this is another question, but it's much more difficult to answer.

Installing the Mac OS on a non-Apple computer is always illegal even if you own it, because Apple's EULA (unlike TI's) forbids you to do that.
Really? That'S weird, I would have thought that normally we got full rights to do what we want with what we buy (except killing people and stealing stuff, for example).

Also if it'S really legal to install a CAS OS on a non-CAS calc, then why was RunOS never released?

That's what you're allowed to do by default, but software licenses are very common and they usually attempt to restrict your rights by not allowing you to do more than running the software. It would be good if we had the rights to install software however we want to, but we sadly don't.
Also if it'S really legal to install a CAS OS on a non-CAS calc, then why was RunOS never released?
The sites that such a program would be hosted on might end up in trouble, since TI might have done something similar to what they did when the OS signing keys were released - the materials are legal, but TI doesn't like it and thus they send DMCA notices to try to take it down. The Nspire might also end up in trouble on tests if it can run CAS OSes (but that doesn't seem to be a problem now even though OSLauncher exists). I'm not completely sure about why the author didn't release it, but I think these reasons are likely.
