Not exactly, but now that you're asking... I use them for exploring things and personal calculations, they're great for this, and for some exam akin to FE that I'm pondering. But for real work? you had to be out of your mind.

Save for specialised user cases, surveyors or I don't know, pilots, machinists? and maybe a few more, you can't publish things done with a calculator if you want to be taken seriously. It's been a long time since there's much better software out there, better as in standard, reproducible, more accurate and quite often more learned (Excel? not really. It's actually pretty good for many other things, though). And if there's not, you're expected to create it using a good compiler. This is 2014 and people have access to computers.

Keep them for blueprints, but then you have to calculate your final numbers with the real toolchain.

Let me get a handle on this please. With what your stating, how usable, reliable, relevant, essential and valid were the dozens of application packs for the 67/97 and HP-41 since these calcs were equipped with the mathematical shortcomings we're discussing here?
