I'm a 2nd-year EE student, and I've hit the point where my TI-83 won't do everything I need anymore (specifically, reducing matrices of complex numbers). The class for which I need this (for now) allows on exams any calculator that doesn't have wireless communication.
I believe this is the case for several future classes as well. Anyways, the TI-89 is pretty expensive for something so low-powered. I'm thinking of possibly getting an HP-50 or some sort of Casio (the Prizm sure seems sexy). How do these compare in features to the TI? Can they solve complex matrices? Can they do exact-value calculus like the TI?
Are they as easy to program as a TI-83? EDIT (since I'm still getting the occasional comment on this): I got a TI-89. I don't know how I ever lived without one before.

It's basically the closest thing to Wolfram Alpha or Matlab that can be used on some tests. I have pretty much every major calculator. Used to collect them.
I never touch my TIs anymore. The deal is this: the TI-89 comes much closer to being a Matlab station for a newbie. The pretty print is easy to use, the apps are user-friendly, etc.
Once you're done with this highly artificial situation in which you can't use Matlab and you do want to solve complicated problems, the TI will suddenly be useless. Too many parentheses, too many function calls, too much focus on math as it appears on paper.
It's like using a GUI to write a book by clicking through a list of words. Easy learning curve but a low top speed. RPN absolutely lets you rip through practically any problem that is suitable for a calculator. The speed advantage is huge.
