So the tablet they are using from 8:00 to 10:00 is a Kindle Fire HD not a Galaxy. The only name I heard was when earthling (whatever his name is) said 'we did it with a galaxy s4 at 10:00. Regardless, they were chromecasting netflix not tab casting from the tablet. I don't think that can be done, so I am in no hurry to install a rom that supports chrome.
I have play installed and I suspect lots of apps are going to show up for the chromecaster. Should be fun.
