The original Glass cost more than $1000 and lacked of enough apps. But a new version could
prove useful in certain work environments, such as healthcare professionals, mainly for
hands-free recording of information and surgical training. It could be also used to promote communications and external marketing through easy capturing of video footage, or as a new communication channel in the work environment for more effective collaboration and distant communications in tele-conferencing.
On the other hand, the market of wearables and connected devices keeps growing but we'll have to wait a bit more in order to see whether consumers and businesses are ready to include them in their daily tasks. And Google is obviously waiting for a more receptive environment for the next version of Google Glass.
