Keyboard lets people type so fast it’s banned from typing competitions
The "500 WPM" video is a little suspect. He types literally one  memorized sentence and extrapolates a WPM from that one 10 word sentence. I'd like to see him actually type 500 meaningful words in under 60 seconds.Anyway, this is cool but basically just a modern stenography device. Steno has a learning curve problem that makes it so most people won't use it.
