Tomorrow, for one day only, anyone in the United States will be able to purchase Google Glass. Where previously interested parties usually had to sign up to waiting lists or get referred by a friend, the company is making a limited supply of its wearable product available for $1,500 from 9AM ET on April 15th. Ahead of the sale, Google has detailed the next round of updates for its device set to roll out later this week, including Android Kit Kat support, improved battery life, and the removal of video call capability.
