Taking full advantage of the metro design, NBC Nightly News lays all the daily news items across a five page hub. The app does feature Brian Williams a lot but also brings you news videos, full broadcasts of the news show, and categorized stories ranging from politics to weather.
There is also a Facebook tie in that allows you to share stories on your Facebook wall. NBC Nightly News is a free app and you can find it here (opens Zune) at the Marketplace.
Thanks goes out to Amir for the tip!
