Example Input: (Ars Technica) -- These days, it seems, it's not enough for a digital device to just play games. To keep up with the smartphones and tablet computers of the world, any game system needs to at least nod in the direction of cloud-based and social networking "apps" that are all the rage with the kiddies. Sony's PlayStation Vita has now done exactly that, launching free downloadable Netflix, Twitter and Flickr apps in conjunction with the system's official debut Wednesday (though pre-orderers have had the system for a week now). Your very first encounter with two of these apps foreshadows the occasionally awkward experience to come. When you first load up Twitter or Flickr on your Vita, you're asked to click a button that opens up a web browser where you can log in to the service.The PS Vita is primarily a gaming device but also runs apps for Netflix, Twitter and other servicesThe Vita screen's resolution isn't quite "HD," but high-definition content still looks goodYou can easily search through tweets with a handy conversation viewFlickr has a nice interface with quick access to photostream, favorites and contacts

Example Input: Hong Kong (CNN) -- The naughty step is not working. After the United Nations slapped tougher sanctions on North Korea after its third nuclear test in February this year, Pyongyang screamed in defiance. It canceled its hotline with South Korea, withdrew its workers from the Kaesong industrial complex it jointly operates with Seoul, and carried on with its over-the-top threats. China may have backed those sanctions but the economic lifeline is still there. Trade goes on between North Korea and China. In 2011, before some of these trade embargoes began, China accounted for an estimated 67.2% of North Korea's exports and 61.6% of imports, according to the CIA World Factbook.Pyongyang reacted angrily to tougher sanctions after its third nuclear testChinese trade with North Korea has been a lifeline for the isolated regimeBut Beijing has struggled to control the angry rhetoric from its neighborExpert: China fears a North Korean collapse would spark a refugee crisis

Example Input: Crown Princess Mary demonstrated the royal way of showcasing a hint of skin during an event in Denmark last week. The Danish Royal attended a children's library in the city of Odense to launch a summer reading campaign wearing a chic cream and navy ensemble. Mary, 43, wore a blouse that could be either demure or daring, depending on how it is worn.

The striking blouse was lined in navy to match her textured knee-length skirt, and patent navy heels.
