Most people who buy Glass probably aren't looking to be inconspicuous. Until very recently, Glass was only available to a select few, and its $1,500 price tag turned it into a sort of status symbol. If you strut through a busy city square wearing Glass like it's a tech-version of a purebred purse dog, you'll likely draw attention—but it might not be the kind of attention you seek. If someone asks about Glass, or perhaps, makes a disparaging remark, don't be confrontational. If the question is reasonable, answer it to the best of your ability. If the question is not reasonable, walk away and remove Glass, if necessary. Don't act entitled and/or defensive and make the situation worse.
