I had the last version of the CAS calculators and went back to my 84+ silver because I hated it.  For even simple functions you had to go through 2-3 menus...navigation in general sucked on it.  I wish TI would step up to 2011 and go with a touchscreen and at the very least, a QUERTY keyboard...and let the trig functions keep their own keys like on the TI84/89 series.

I have one Casio calculator and it is a Casio fx 115 ES. Not a bad little calculator and it is better than the Texas Instruments TI-30X IIS Scientific Calculator  I bought from walmart. My TI-89 is a pretty good calculator but I am thinking about getting the Nspire
