Remember a couple of things:
1) The keyboard of the 30b can be fairly easily redefined to "assign" a function in a menu to a key location. If you don't like the trig functions (which I suspect are there to let people KNOW they are there), and would prefer to have DATE and DDAYS on the keyboard instead, that is easy enough to do. Make the machine like you want it. Same thing with STAT functions. Want mean and standard deviation on the keyboard? Easy. This is described in the 30b learning modules with examples.
2) After having used the 12c for nearly 30 years, authored a textbook, and even taught college classes in finance with it, I'm well aware of doing things the "periodic interest" way as well as converting interest rates the way the 12c requires. However, I do believe that interest rate conversions are easier done with the ICONV approach on the 30b.
3) The shifted STO issue is one that is brought to HP's attention quite a bit at HHC conferences. It seems the view is that people tend to store less often than recall, so they do it this way.
4) The 30b is the first HP financial model that a college student could buy and use for all their classes...business, biology, chemistry, math, etc. That's one reason it is done as an "all in one" model.
5) Keep in mind the incredible extra features the 30b has compared to my beloved 12c. Such as...
Built-in probability distributions and inverses for FOUR distributions. Wow. Standard error of the mean, covariance (a first!), multiple regression models, black scholes, MIRR, and lots more.
I understand your dislikes. Truly. I think many of them can be "fixed" using the abilities of the 30b.
I rarely pick up my 12c any longer. I cried a lot at first, but much less now. :-)
