You seem very determined to be disappointed by this whole discussion. If you completely close yourself to new possibilities, nobody can force you to consider them.

You said:

> 6+ hours and hundreds of comments later I went through the comments and I still haven't seen anyone post a single mechanical keyboard that matches my requirements at any price point.

I was just offering one keyboard which does as far as I can tell satisfy all of your requirements. (The previous $250 version of this keyboard is about the same as this $350 one; the differences aren’t IMO worth the difference in price. You could probably find a used one for $150, if not less.)

Here are some of the features that make the Topre board nicer than your Amazon board:

- The actuation point is about halfway through the stroke instead of at the very bottom, meaning you don’t need to mash the key all the way down to get it to reliably actuate. Once you get used to this you can type with much lighter and springier finger movements, and (a) dramatically reduce the amount of shock on your finger joints, reducing both fatigue and long-term damage, while (b) improving your typing speed.

- Having taller keycaps on the further-away rows of keys compared to the home row makes them easier to reach by extending the distal joints of the fingers instead of moving the hand. It is in my opinion inexcusable for keyboards not intended for laptops to be flat across the top. Additionally, the keycaps have a curved top shape which helps the fingers find them.

- The switches have what many people find to be a more pleasant tactile response (this is subjective, and I prefer other keyboards, but those do not satisfy your other criteria). I would expect the 45g Topre keys to need less force than the Amazon board, but I haven’t ever seen measurements of that one. (Some people prefer heavier switches; Topre also makes a 55g version. Some people prefer very light switches; Topre also makes a 30g version.)

- In particular they have a nice bit of bounce on the upstroke which will help your finger to release the key just by relaxing the flexors instead of needing to fire your finger extensors. This will (a) reduce fatigue, and (b) improve speed and accuracy.

- The Topre keyboard is likely more uniform from key to key. Most <$20 rubber dome boards have poor quality control. (I have not tried the Amazon one.) It should also retain its key feel better over time.

- I would expect the Topre “silent” board to be quieter than the Amazon board, but I haven’t spent much time with either one, so you’d have to test that yourself. Personally I like much louder keyboards.

- The Topre keyboard is much more robust; the switches use capacitive sensing to tell when the spring has been depressed, instead of relying on an electrical contact, so they should not wear out even after tens of millions of keypresses.

- The Topre keyboard has larger rubber pads on the bottom, probably made from a nicer material. It should slip less than the Amazon board (being heavier also helps with this). It also has nice sturdy feet if you want to adjust the tilt.

- The switches are very stable and smooth, with tighter tolerances. The keyboard is much more rigid and solid feeling. Overall it feels like a well engineered product instead of a flimsy toy. Many people find joy in using well made long lasting tools, but YMMV.

- The keycaps are made of a sturdier type of plastic, and use dye sublimation printing. The letters will never wear off, and even the surface texture should remain through decades of serious typing.

- The electrical components inside the keyboard are more expensive and less likely to fail. You’d have to test latency, etc. for yourself, I haven’t extensively evaluated either of these keyboards.

- The keyboard supports full n-key rollover (this is unlikely to matter for routine typing).

> how is your recommended keyboard different than a run of a mill $50 mechanical keyboard

The switches feel substantially different. The keycaps are made from a different type of plastic. The case is sturdier. The switching mechanism is more reliable.

But keyboard preferences are subjective. Personally I like many $50 keyboards better than this $350 one. I was just looking to satisfy your criteria.
