Thanks, Bob!!

But most often, for haughty calculation challenges like household chores and checkbook balancing, I prefer the 48SX too, especially those with the LCD replaced by a Black one from a later machine. Perfect aesthetics...

I can so agree about the aesthetics! And, no, I don't need to run huge multivariate integrations with a bazillion iterations to squeeze out every digit down to the ULP. There's PCs and Mathematica (and other tools) for that.

LOL, what I use my 48g for (and would use the 48s for) is to emulate a 16c but with a big stack display... or run my interval arithmetic library (which is pretty simplistic and computationally non-intensive). It's kind of spiffy for me to just enter approximate values and either a +/- error term or an asymmetric range about each value, and then do my computations and not have to think about how the uncertainty is calculated: it's done brute-force for me and I can see the actual uncertainty right there.

Oh, just remembered, I do date math on it, too. And simple complex arithmetic since it's so easy to both enter the numbers and read the results.
