My take on "ze Germans", "psycho-acoustics" and "badass typists"
First off: As a native German-speaker, I always have to giggle with the whole "Das" Keyboard. "Das Keeboahd. Jaaaa."
Secondly: As silly as "...the psycho-acoustic experience [...] an unmatched typing experience" sounds. I know exactly what they're talking about. And it matters to me.
Maybe, as a neurodivergent person, it's because it provides a stim that I need in exchange for sitting still. So, to their credit, "psycho-acoustic experience" nails it for me.
Thirdly: Not in this lifetime will I buy a product named "Badass4" made for "badass typists" (Honestly, wtf?). I will not get into criticizing the overall shape. That's a matter of taste. Let's just say, the Altair I speaks to my preferences.
