Well, as the product name states, this 15C is meant to be collected, not used. ::)

Interesting (and probably valid :)) observation, but I would definitely use mine. My SwissMicros clone has held up very well to daily use and travel, and I would expect a "genuine" HP15c ...even a "collector's edition" ... to do the same.

The SwissMicros keys are beveled - see attached

I spent a month's worth of food money to buy an HP48G in graduate school. Lost some weight, but it was worth it :)

Was kind of the same with me. Saved up a whole year of pocket money to buy the HP 48GX on my summer holidays in Germany. In Portugal this machine was not available.
I purchased a software collection, too. It came on 3.5" HD MS-Disks, which my Amiga 500 could not read, so I spent quite some time at my friend's home converting to low density disks... I discovered that most cool programs would not run on the GX because they way made for the SX.
Still it was (is) a great machine. I became an "A" student thanks to this calculator. I programmed all kind of exercises to automate whatever came up in exams. One example was the SIMPLEX algorithm. While others failed to get the right result due to numerous calculation errors when dealing with the matrix, I had my own software that would print each step: I just had to copy the results to the exam. Don't consider that cheating, because I developed the software myself as a form of studying the subject. Had this approach on many courses. Helped me to stay interested in the otherwise boring subjects, while getting the exercises 100% right... Good old times.
It is kind of sad that you face so many math problems during University and then, when you start to actually work, Excel is often more than enough...
Sometimes I just use a CAD software to calculate the intersection point of to curves or whatever. Why calculate manually?
Yesterday, my students pointed me to this site: https://www.integral-calculator.com/
It is free and helps with integrals in a mind blowing way (compared to what I had available in the 80ies/90ies).
Still wondering if I will shell out 129 Euro or not...
