The PS4's lack of DLNA support will likely affect only the most tech savvy PS3 users--but for some, this missing feature is a dealbreaker. What do we mean by DLNA support? Let's say you have a PC with tons of movies, musics, pictures, and other media stored on it. With the PS3, you could access those files by networking it with your PC, then play them on the big screen. Basically, you could stream all the media you own and have stored on a device through your PS3. Pretty cool, yeah?
The PS4, however, doesn’t allow for such a setup, as it's more of a "closed" system than the PS3 was. Want to watch movies or listen to music on Sony's latest machine? Then you're going to have to pony up some cash and subscribe to a few of the many media apps available. Not that said apps are bad, but DLNA support is an alternative that we're eager to see return.
