>The first part would be kind of cool, I guess, until everyone buys their google glasses
I'm not totally sold on google glasses. People look retarded trying to focus on the glass. Apparently it also makes people feel nauseous if you wear it too long and you need to "learn" how to wear them.
Either way, Pebble and google glasses are both part of a trend towards wearable computing. It will be interesting to see what kind of crap companies try to get us to walk around in over the next few years.
