I agree with the general takes here, and can add one for specific situations. I have some very old keyboards, and frankly even my newer ones rely on designs that are over 40 years old. In this particular case, I find the old tech superior, because they simply feel nicer to type on, and that’s what a keyboard is for.

I also have quite a few fountain pens, but whereas with a little effort the keyboards are as good or better than an average modern model, I’ll admit there is a fussiness and mess with fountain pens you have to weigh against the nicer writing experience.
