Ya have to be careful with with using an RPN calculator for school.
They can sometimes be banned due to their programmability.

You don't want to get used to using RPN and then on the day of the test find out you can't use it.

Also the teachers don't like you using a better calculator than theirs.  8)

I "grew up" programming my dad's TI-59 (479 programming steps and 100 numbers stored!), moved to a Casio fx-39 (fluorescent display - yeeees!) and then got a HP48SX that helped me through college. I then got a TI89 Platinum as a gift from a friend and my wife gave me her HP48GX after my SX died...

I also use a HP48 emulator on my phone, which runs faster than the 4MHz Saturn processor of the real deal. However, doing calculations on a real keyboard is a lot better.

Also, although the TI89 is an excellent calculator, once I got used to RPN it is hard to give up...
