(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
