HP-15c: Why so popular?

[Peter Klein]

Pardon me if I question Doctrine here ;-). I’m curious why the 15c is so popular. Don’t get me wrong, it’s a very nice machine. HP managed to cram maximum possible goodness into a limited but lovely, elegant, durable package with a beautifully readable display. And I used an 11c as my daily driver for a dozen years, so I have some idea of how it feels. *

But the 42s is much more easily usable for complex numbers and matrices. Solving equations and programming is much easier on the 32s, 32sii and 42s. And then there’s the equation list, which the 32sii and its red-headed stepchildren the 33s and 35s do and the 15c doesn’t.

So, in 25 words or more, tell us, “Why I love my 15c, despite all that’s come after it.”

* My opinion may be colored by the fact that my hands are too big to comfortably “touch type” numbers on a Voyager.
