After a public release that generated few sales and even less consumer excitement, what went wrong with Google Glass?

The quick and simple answer -- the device is still in the beta test stage. Google Glass is still at an experimental level, and is being tested by different professions for different uses. At the same time, the futuristic gadget was made available to tech consumers, but admittedly, it is still very much a prototype

It's expensive. At $1,500 without taxes, Google Glass is not easily within economic reach of the typical consumer. So far, its release has only excited the rich early adapters. It may take at least a couple of years for it to gain momentum and reach the mainstream tech market. Even still, there are skeptics who believe that it will never fly.

It's not ergonomic. People who wear glasses know that there's no such thing as a one-size-fits-all pair of glasses, something which is even more true for this gadget that is straight out of a sci-fi film.

Users may also find a level of discomfort while wearing it because their eyes will have to adjust as well. The gadget will restrict peripheral vision and the user will see it the entire time they are wearing Google Glass, and being able to see and feel it can become cumbersome.

Furthermore, it's not exactly hands-free. Google Glass can't be fully operated with the eyes yet; it requires users to a number of finger gestures. Also, voice recognition could be an issue.

Finally, the market is not yet ready. While technological advancements are very much welcome in this golden age of technology, people are still struggling to keep up with the fast pace. Consumers have not fully maximized current product offerings and are still enjoying their current features; there is currently no need for another jump to an even more advanced gadget such as the Google Glass.

Google may have its time in the future. But for now, Google Glass remains a luxury for the tech-obsessed.
