With all the controversy being generated around this device, Google must be rubbing their hands with glee as far as publicity goes. However I still fail to see the attraction for Glass - I personally couldn't think of anything more distracting. There's enough tech around me performing this function to varying degrees already.
If privacy is a concern, my observation is that these days it's mostly an academic one - regardless of what corporates or governments may say, your electronic presence has value to them - that's not going to change.
And as far as advertising goes, nothing Google, or any tracking/collating service on the interweb has served up to me (mostly unbidden) has peaked my curiosity to the point of further investigation - people reach people, not algorithms IMHO.
So, are these really game changers, or is the hype exceeding the reality - I'm genuinely curious.
