I *just yesterday* threw away the HP15c I'd used since 1988 (sniff, sniff - really).  That was an awesome device reminiscent of the old HP back when it was a neat company.  For $9 I bought the 15CSciCalc app, which was well-appreciated by previous users.

97.0870e-5

But holy crap!  That's relatively unimpressive!  Does someone have a real HP15C so I can compare the hardware device's results to this app that is supposed to duplicate its circuitry?
