After a few months of testing, the feature that allows Chrome OS users to stream videos from Google Drive storage -- like the free 1TB allotted to new owners -- to a Chromecast is now available to (almost) everyone. An update on the stable channel this week pushed it to most people, with the exception of a few devices: the Dell Chromebook 11, HP Chromebook 14, Acer C720 and the Toshiba Chromebook. One thing everyone with the Chromecast dongle can appreciate are additional backgrounds, this time provided by NASA. To access them, pop open the Chromecast app on your mobile device, select "Backdrop", go to settings and choose NASA.
