This is my iPhone 6+ calculator. You'll appreciate it:

I bought my 11C and 12C calculators in 1980 or thereabouts. Those were the pinnacle of perfection in my book. They are still going strong, but I've switched to using the RLM calculator on the iPhone because it is always in my pocket. There's an old saying about cameras that also applies to calculators: "The best camera is the one you have with you."

The same is said about firearms.

Thank you, FRiend. I just bought the app....It doesn't flash 'running' like the original 12C did when it calculates the IRR but otherwise it's AWESOME, TOTALLY AWESOME!!

It is also beautiful...like a piece of good modern art.

And thanks for the HP 12C app, too. Like finding a long lost friend.
