I learned to play the piano before I got into computers and the difference between my teacher's Steinway and my Ibach upright at home wasn't lost on me.
So when I did learn how to type (also an IBM Selectric at High-School), their keyboard quality did leave an impression: I have used original IBM keyboards, XT/AT first and PS/2 until today, produced somewhere around 1991, I think. Absolutely perfect for text entry, but terrible for gaming, because they only manage something like three pressed keys at any time.
These cost something like $2000 new, nothing I'd have paid for a keyboard when I could have more RAM, Hertz or storage, but as great as they were for typing, they weren't compatible with others in the same room. So when they were thrown out by banks squeezing traders into shared office spaces, I got myself the two fine specimens, I planned to use to my grave.
The missing Windows key never bothered me, until Microsoft decided in their infinite wisdom, that Win-Y is non-negotiable as an augmented reality toggle key... Their willingness to yield to consumer preferences is always heart warming!
Recently my primary IBM PS/2 keyboard got just a little bit too much Spätburgunder, so I was given an opportunity to either activate the backup or try something 'modern' for a bit more gaming compatibility. Picked a Cherry, which manages to be even noisier, isn't too bad considering, but nowhere near the same quality... albeit much better for the casual game, even if the right Windows-key is driving me mad, because my thumb keeps hitting it when aiming for the compose key.
You see, I deal with four human languages on a daily base and then there might be some coding, too. The primary layout is German, which works fine for English, too, but coding either means switching to a US layout for easy access to all these special chacacters or, ...plenty of compose action. For Spanish, I tend to go with a Spanish layout, but the French AZERTZY layout might as well be Dvorak: No way!
QUERTY has been criticized a lot as being far from optimal for fluent typing, but personally I can only assure you that you're still quite lucky to type in English. I've never achieved near the fluency in German, Spanish or French, quite simply because the same fingers need to move far too often for a word. In comparison there are tons of "arpeggios" (a sequence of keys pressed on a piano without releasing the priors) in typed English or combinations that switch the hand so the fingers have more time to move to the new position. Consider words like "there", "though", "what" or "you", which just flow from your fingers. Their Spanish equivalents will be a letter or two shorter, but more staccato and then you need all these extra vowels in front and in the end which enable Spanish speakers to sustain the air flow required to make your self heard over dozens of people in a tiny room with hard surfaces speaking at once.
In my case the brain is still the major obstacle to my writing speed. The most important benefits of having learned how to type properly is a) being able to look at and read what you produce and
b) the low barrier to replace it with something better.
And there the strict discipline required by coding in programming languages might have had an influence, too. I can see people break typing speed records in COBOL, but not in APL!
