We have some good news, and some bad new. First, the good news: Redbox Instant was just updated with support for the Nexus 10! Now you can stream movies to your heart's content on that big, beautiful display. Fantastic.
And the bad news: it still won't work if you're rooted. So, if you were rejoicing that you can finally use it on your N10, you can probably stop now if it's rooted. Sadface.jpg.
Past that, this update "squashes some bugs." So, maybe if your device isn't rooted, it'll suck less now? Can't really say for sure since, you know, I can't actually give it a try.
