I've got the 50G, and really enjoy it. It's very powerful, and I find that the RPN mode is so handy that I can no longer do math correctly on calculators without RPN mode (or at least at nearly the speed as I can on my 50G). One side benefit of RPN is that you can save intermediate results very easily by just duplicating them on the stack. Apart from having to teach myself how to do a couple things on it in high school because the teachers had never seen one, I've never found anything that it couldn't do that a TI could.
