Not to mention the lack of combinatorics and hyperbolic trig (good thing it already has e^x-1, since I don't know a good way to calculate it without sinh).

The nice thing with the 41 is that you don't need to have everything on board: if you want something exotic just key in the program from a Users' Library Solutions book or, better, plug in the required module.

Yup, that's the big advantage. If it didn't have the extensive memory and expandability, I probably wouldn't give it a second thought, and just stay with my 32S. It's still odd that some of those basics were omitted, though. Linear regression is missing as well. I wonder if they had to keep ROM size down to allow for enough RAM at a reasonable price point.
