Google could probably price the glass for just a few hundred dollars, but they don't. Why? Because Glass is not yet a polished consumer product with apps/features that create a compelling reason to wear them all the time. Google is releasing them intentionally to 'thought leaders' who will critique and come up with the ideas for features that will make Glass broadly compelling to consumers. By the time Glass is released as a mass market product it will already have app store loaded with apps. Seems like a simple strategy!
Looks nice, will try it on the web app I am currently building with Meteor. Does it or will it support migration of MongoDB data from different instances. Say for example, I've deployed onto <some_domain>.meteor.com and next want to deploy to a production instance at modulus.io, then migrate my data.
