is it worth buying an hp 48gx or 50g in this 2023?

One of the machines in my regular "daily driver" rotation is a 48g.

Even though I now use less than 10% of its overall functionality, it's still a joy to use, for its multi-level display and unlimited stack. I have an interval arithmetic library I wrote for it: not perfect, but still very good for when I am doing calculations with lopsided uncertainties or different ones in different steps.

The built-in date/time math is also easier to use than on some of my other models, so it's my go-to calculator for that as well.

I've never tried carrying around a calculator this large, but mostly I am near a desk at most times now, and can easily just reach for it if I need it.

So, yeah, 48gx or 50g+, still a good investment!
