Glass
Anyone want an unsolicited opinion? waits for everyone to leaveI hope Google Glass is an experiment, because voice reco isn't particularly important outside of when you're driving. When I get tired of texting and consider voice reco, 2 things hit me (and others, I've done solid research on this)1. Voice reco would be slightly better now that I'm tired of texting, but not  much. 
2. It is nowhere near socially acceptable to be speaking to no one. That's why you only see old people using bluetooth - how is that not an unbeatable sign? You can't just be speaking to no one.The next step in communication has to be either low input "aware" communcation (aka, the check-in) or communication that somehow otherwise reads your mind.
