One can also look at distinguishing what is important to what is unimportant to a particular person. Personally, I look towards functionality over aesthetics. That isn't to say that I will completely disregard aesthetics, but I have certainly gone with those black bricks called ThinkPads over MacBooks in the past.

You are right about it cutting both ways though. I remember laptop shopping with a colleague in the past. They were trying to replace a barely functional laptop that they purchased because of its "design" with something they could get work done on. Unfortunately, they refused to acknowledge that functionality is an element of design. The whole experience was one of frustration.

This calculator appears to fit into a similar category. I'm sure it is a perfectly fine calculator, functionally speaking, if you are performing basic financial calculations. It isn't going to cut it if your working outside of that domain. When you consider that a calculator that is a tenth (or even a hundredth) of the price is going to offer a similar experience, I'm not even sure I would regard the nuances in its design a good thing. Yes, it says something about it's owner. I'm just not sure it says the right thing.
