Wow, people, realx. No one is forcing you to buy anything.
As far as the article is concerned, the analysts got it all wrong, IMO. The hardware development will dictate how soon will this technology take off. It is the opposite of what they say, because people are more aware of what they wear in public, and right now the Glass hardware looks too geeky for mass appeal. The software, OTOH, is already available to certain degree, a lot of apps can be made to run on this with minimal modifications, and even fewer apps are dedicated exclusively for Glass, but that will evolve rapidly now that developers got their hands on prototypes.
