Good start, but your are missing a few things too. For example the culture of mechanical keyboards, or more importantly how that affects buying them for the first time and, when the time eventually comes, replacements.

Want to be able to replace your keyboard, or get another one for the office easily? Buy a Cherry G80-3000.

Want to get used to something only to find it’s incredibly hard to find a second one that matches your muscle memory? Get an RGB Vortex racer 3 pro or an AKKO3068 with a custom run of SA double shot hello sushi keycaps in limited edition dat boi green.

Want something that you can place in a backpack and not cry about when one of the 1000 tiny little bits of plastic — all of which are critical to the keyboard operation — snaps off as you pull it out? Keychron K1 or one of its siblings. (And this isn’t a slur on the K1’s build quality — all keyboards are, by their nature, delicate devices.)

I own all of the above and more. That’s not a flex. I’m an idiot. If I did it all again I’d buy a six pack of K1s and stop there. Unrelated: can I borrow some money?

(You have a typo fyi: “there are mainly four types of switches: black, brown, green, and brown”.)
