Just like any Android device the fun really happens once people start hacking and sideloading apps. Google Glass seems to be no exception as root is fairly easy to obtain. Now we also have confirmation that you can even sideload native apps on the Google Play Store thanks to tinkering by Ron Amadeo from Android Police. He got his Google Glass a few days ago and has been testing what he can do with it. It seems that you can hook up Glass to your computer with debugging enable and use ADB to sideload apps. What apps install and what can you actually do. Checkout the video he put together. It’s pretty neat.
