My list of must-have android apps on my phone and tablet include
Droid48, which is an android port of X48.  Runs the original firmware
and everything.  Works very well for me.  Of course I also use my real
HP 48 on regular basis.  The poor thing is 20 years old now but still
the most useful calculator I've ever owned.  I get lost on calculators
without a stack and RPN.  Had a debate with m boss over RPN though.  He
claimed it was just HP's engineers being lazy.  For me RPN on a stack is
faster for me than a normal calculator because it's closer to how my
brain does math--you have to manually do order of operations on paper.

Just the other day I learned how to implement custom units on my hp 48
and have them automatically convert to other units.  Very cool.
