The hardware is certainly a potential game changer, but only in the sense that it provides a clear direction for how we might close the gap between interaction in the digital and real world. However, the game which is badly in need of change isn't being addressed here.
A $1500 beta price point is sadly not unexpected. By design it serves a purpose of restricting the origination of innovation and limits the potential for wealth generation to be equitably accessible.
Because this is the case, glass isn't a game changer in the way it potentially could be, and instead is just another addition to a profit only purposed corporate tool box.
with an outlandishly high entry fee for participation Google is saying their sole aim here is protect the status quo of who is able to participate, shape, and profit from the eventual marketplace.
This price point is nothing but a pay to play scheme. When they eventually launch the consumer version of the product there will be a small marketplace of initial applications developed by the chosen few who could dish out $1500 for each unit of hardware they may require to properly realize the purpose of their vision.
Per usual practice of Corporate profit driven power, any new innovation post consumer launch will likely be cannibalized by those players who were fortunate enough to afford making use of their creative skill set during the beta leaving the rest of the market to be quickly bloated with unprofitable applications unable to get a competitive footing, or simply stomped out of existence through patent law.
Sadly it seems the once very open digital world, and its traditional defenders have failed miserably in changing the real world. Unable to beat them, they instead have joined them. Innovation is great, but opportunity is better...
