Prefer BA II over Hewlett Packard 12C

I bought the 12C when it first came out in 1981 because I was a Real Estate Broker. I broke or lost at least three of them. I still have a broken one.
I switched to TI 59 ($300) because of my accounting degree. Found the programming easier than RPN for a non science major.
As a RE Broker, the TI BA II had everything I needed for TVM so I sold the TI-59 in favor of the TI BA II.
Features that I like: uneven cash flow, IRR, begin/end of month.
Ive bought, used, broke or lost at least 6 BA II Calculators.
I still have 2, including one that works.
But I dont need it now because this app does everything the hardware calculator does and its always on my iPhone 3GS.
