> How many iphone 13 minis have you used concurrently, and in how many different locations did you own them? Byb your own admission, you only use one at a time.

It's not about concurrent use at all. It's all about availability. I had my simple, trusty Logitech keyboard and mouse. And 2x more of each, in a box, in a cupboard. I'm not using them. But I have the comfort of knowing that if either fails, I'm back up again in two minutes. That, for me, is comfort.

Now, if I had two workplaces (for example home and the office) would I carry my hardware between places? If I can't afford to buy two of them, yes. But if I can afford to pay 20€ twice, I'll have one keyboard at home, the same keyboard at the office, and so. That, for me, is comfort.

Now, scale the keyboard for 20€ to a Lexus for 40k€. Same thing.
