"How many times have you been in a conversation, and picked up your phone to Google something you’re talking about. And after reading the result, you check your homescreen, and a few seconds later, you’re reading your tweets or your Facebook newsfeed, and no longer contributing to the conversation? Being able to ask Google anything and instantly get the answer without having to use your phone is magical."

This is a problem of focus and attention, not an interface problem. If you play with your phone when you're supposedly spending time with friends, glass is just going to make this significantly worse (because now you're looking towards me but still scrolling through your FB feed).

"And with Google Now, you know how bad the traffic is and how long your ride home is going to be without having to ask for it." I use a better solution today. Waze has routed me around traffic jams with amazing success, and it didn't cost me anything (since I already invested in my smartphone).

Everything I've read on glass so far seems to be taking some big leaps to justify the device. As others have said, it will lead us towards some interesting solutions eventually, but it is definitely not the best solution to ANYTHING.
