Google Glass (or Google Glasses as they are also called) is not (or are not) going away soon.
I have suggested in another blog that mobile devices have beecome much to complicated. Google Glass simplifies the user experience in ways that the smartphone does not. See Smartphone As Screwdriver.
And on that score alone, it will be worthy of serious consideration, although the price will have to decrease substantially before it will be adopted widely.
