This mirroring feature is why I got the Chromecast in the first place. And I love that feature. Have a few issues with sound not working sometimes, but overall it's a cool feature. I also have a Roku 2, which JUST added Youtube, which I used a lot when I first got my Chromecast. Now I'll be using Youtube on my Roku, since it seems more stable than the Chromecast when streaming Youtube. BUT, I'll be using the tablet mirroring quite often. For an example, I'm a hockey nut, love the NY Islanders, and they were streaming a rookie scrimmage game on their app, I was able to mirror it and watch it on my 46" Samsung TV ! Technology is amazing !
