This is where I disagree. I had severe hand and arm tendon pain for years, and finally dove into ergonomic mechanical keyboard options. It solved my issues, and I no longer feel the pain after typing all day.
I easily spend $350+ for a keyboard, and it's a very practical, life-changing decision, which involves a non-rectangular, non-RGB keyboard.
