This is a revolution in the storage. It is wireless remote storage that can multi users share their media. therefore, the user do not need to email or cloud and free charge also. The author in this article mention Wireless Media Device from SanDisk company as an example which has free apps for Android, iOS, and Kindle Fire to connect device with the storage.
In my opinion, this is the best way to share a huge media just when the users in the same building. All companies produce similar items should focus on families, activity groups, and media companies.
The travelers or photographers can use it to share their pictures and videos from smart phone or camera to the storage ( 8hours rechargeable battery) like backup, then get it from the storage to laptop or PC easier by wireless.
