Windows Pick: Unstream
Paul Thurrott's pick on Windows Weekly 463 is Unstream. This is an unofficial Twitch.tv app, and it's universal Windows platform app, which means it works on both PC and mobile. You can watch live streams or videos on demand, search for games, channels, or streams, follow and unfollow channels, and get notifications and Live Tiles when followed channels are live. There's also a custom stream/chat experience.
