Re: 15C re-release may be a good time to remind.. Message #3 Posted by Mike Morrow on 14 Sept 2011, 3:44 p.m., in response to message #1 by Pal G.
The advanced features of the HP 15C are not very simple to use, but in 1983 (the date of the cited paper) the 15C was the best thing out there for complex domain, matrix, integrate, and solve functions. Not even the HP-41 series with Advantage Module matched it.
But...having spent more time since Friday with the 15C/15C-LE than I have since a HP 42S replaced my 15C 15 years ago, I can say honestly that I'd forgotten how terribly awkward and convoluted it is to use those features. But...it is pretty, and isn't that the most important thing? :-)
Simplicity of use had to wait for the HP 42S, a monumental and stunning advancement over the 15C. It is bizarre that some fall head-over-heels for 30 year old yet oddly immature technology, as opposed to 20 year old mature technology.
