It's a vanity item, like a Rolex watch, and its existence is not for actual utility.

Utility-wise for the cost, it's not outstanding compared to regular calculators. If you spend enough time with S100X for the cost to be justified, then you are wealthy or you are spending way too much time at the calculator and should reconsider your workflow, e.g. using a spreadsheet or Python script instead, and those things are cheaper than this calculator.

Nothing wrong if anyone wants to buy it. But technically there is nothing special here, just the physical appearance/build.
