My experience is like a mirror opposite; nearly all mechanical keyboards are less than 100%, and my productivity would nosedive if I had to hunt and peck numbers.

You might not be wrong overall, but I thought it was funny that my anecdote is fully the opposite.

It probably depends on use case. There are plenty of situations where having numpad on the right makes perfect sense for right handed people.

But I’m an oddball who is very much right handed but uses the mouse left handed because my right wrist got so much wear and tear from early life data entry work.

Never knew those existed, really cool. I'll try to remember that and consider one once my old one dies, which by the looks of it will take another decade.
