Why not the long-lasting 15

[Matt Agajanian]

Hi all.

Several thoughts are running through my mind as to why the only V'Ger (I know, Voyager. Yup, A Trekdom reference) hasn't endured the same manufacturing lifespan of the 12C.

Thoughts:

1--Was the 15C-LE too buggy as to seal the demise of a resurgence of the 15C

2--Despite the lack of matrices support, since the 35S and 33S were robust with RAM, was a 448-byte 15C too limiting?

3--Now that we had the 48 Series and 50G, and their feature sets included dynamic RPN stack, matrices as well as symbolic mathematics & calculus, these were far more versatile than the 15C or the LE?

4--Although engineering and users in the sciences are numerous and loyal to HP, the 12C's user base was far more established and populated than an RPN or 41/15 user base?

So, what are the reasons why the 12C is the longest running Voyager series calculator?

Thanks
