This is a great niche product, IMO, other than that it will suffer an embarrassing death. Most people do not need up to the second information while out and even those that do (say drivers) will probably be distracted by them.
Brin did make a fool of himself when he said that phones are emasculating, essentially saying that using Glass is cool. I guess that's an opinion, but I disagree. Unless it's part of your job, you'll look like a pretentious, know-it-all @sshole. And unless you're careful you can subject yourself to physical harm, like if used in bathrooms, bars, getting in people's faces with it etc.
This got a lot of press because tech bloggers, professional "early adopters" and wannabe cool techies are bored, they needed a new product to hype to death and to show how hip they are. It's been a while since a new gadget came out.
