I haven't tried it.  I did read TI's web literature on it.  You're 
right, the CAS version of the TI-Nspire can not use the alternate 
keyboard -- the alternate keyboard is there to support the TI-84 Plus 
compatibility mode that the non-CAS version has (presumably to aid the 
transition to the Nspire by students who learned on the 83 or 84, which 
around here is most of them...)  Maybe the CAS uses enough ROM space to 
squeeze out the 84 mode, and therefore the keyboard couldn't work?  Or 
more likely the designers simply thought that students who were going to 
learn the CAS wouldn't need the 84 mode anymore.  I note that there's no 
84 mode in the 89 either.

http://www.ti-nspire.com seems to have a lot of info.  My 
calculator-lust tingles when I see it, but know I have no use for it... 
  I just have keep telling myself that.
