Bento for Windows 8/RT.
News Bento for Windows 8/RT is a simple news aggregation app that is easy to navigate and presents news items from a variety of sources in a clean view. And, yes, it is free.
Bento lets you select news feeds from a variety of well-known news sources and blogs. The app can also draw any or all the RSS feeds you might collect in Google Reader to let you personalize the news collection even more. While it does not have a way to deal with your Facebook, Google+, or Twitter sources, it is as close you can get to a Flipboard experience on a Windows 8 or RT device. I don’t think it is a stretch to say it may be one of the most useful third party apps available for the Metro UI on Windows 8 or RT.
