Exactly, felt like the wristband was the big thing. I don't want the glasses, but I'm somewhat curious if it'd be useful as an extra input device when using a computer.
And if you really get into them, maybe it's worth spending the time to learn chords instead, like for a court stenographer?
IMHO the tell on why there's a delay is the original comment expressing wonderment at Zuckerberg demonstrating 30 WPM.
i.e. it sucks.
It's nice technology, engineering, glad they had the courage, sure its useful for its purpose.
However, in practice, humans being humans, the odds I regularly put on a glove, to get 30 WPM, on my glasses computer...very low.
(also, looking back at the original comment...neural interface? wtf? It's not neural...)
