i think for us, going even back a year we were talking about previous projects that we have had and we do have ar glasses in the pipeline. we really want to have a conversation, a dialogue with consumers around the world on, yeah, what are the standards and expectations they have for the types of computers that we are going to wear in the future. and this is really our first foray into putting something on someone�*s face, and we're really excited about it and seeing how people react to it. and it is a great product and i have been using it myself but it is the first in a series of products that give people more functionality and more capability through a pair of glasses. that was chris talking about facebook. i really wasn't expecting us glasses. ——i really was expecting those glasses to be augmented reality glasses.
