Google is living up to its promise of making native YouTube TV apps available for the media hub of your choice. You can now add a YouTube TV channel on "select" Roku devices, giving you the service's usual range of live broadcasts, a cloud DVR and the other perks of the cord cutter service. There isn't any mention of Roku-specific features, but the allure is really the freedom to watch in your living room using a device explicitly meant for a laid-back viewing experience.
