They've also not released even a beta of the OS...so meh.
Honestly, I'm just entirely desensitized to technology announcements that don't actually involve a demo of the technology being announced.
It's hard for me to be excited by yesterday's announcement considering there's nothing tangible..not even a closed beta to sign up for or small private demo shown to tech laypress or pundits..something to show anyone outside of the Valve fenceline that this is a real thing.
I've seen so many such tech announcements over the years...not tied to any actual roll-out or teaser implementation, that never actually materialized, that I just don't have any enthusiasm left in the tank for this sort of technology-less technology announcement. Maybe its just me.
Hopefully the rest of the announcements this week will come with something tangible for someone to interact with so they can get authentically exciting by the technology and share that excitement.
