Great Idea bad market
Google glass should have been sold to the military not the general public. The resulting uptake of this product created two types of public, the "haves" and the "have nots" or the "intimidated" what would you think if a person was talking to was wearing "Glass?" What was they looking at? what app was running? it automatically creates paranoia etc.
it was never going to work and as for the price, well, they are not Apple users, they are a breed which often are repeat customers who have always paid over the odds, for the supposed build quality ease of use etc.
Wearable tech should be for the disabled. Google should have looked at their own software division who should have made better apps for their own products, who would build a product and no software to create some desire to buy....oh Google lol
