Google glasses seems to me like an ill fitted concept. It's expensive and you need to wear it constantly. A watch is more discreet and doesn't create that feeling of "I'm being filmed by that person" on those around you.
I'm not sure the watch is a great device for everyone but I think it's a more realistic wearable companion for the phone than Google glasses.
Don't take me wrong. I think technically Google glasses are an interesting engineering endeavor. It's just that I see limited appeal to them.
A watch seems like a good logical step from the Nike Fuelband concept. Track my activity, sense what I'm doing and also display my texts or emails and incoming calls, maybe small maps or very targeted info.
not necessarily...
I wouldn't want to wear those glasses...Especially those people who are not even short-sighted! I imagine that to be very uncomfortable!
