The tech on this thing is so cool and so useless! People will buy them, try them out, and then a month later realize they didn't actually use it at all and return them to the store.
The mere fact that goggles will enable users to communicate and consume media just as they can with devices they already own, will be the key argument to purchase this expensive headset.
But this incremental improvement we get after purchase of each-time-more-polished device finacnces future inventions and innovations, and then after some number iteration we get something that is truly useful. At least that's the trend I noticed regarding every tech breakthrough and hype in this century.
