5.) No DLNA, MP3 and audio CD support… yet.
It was recently revealed that the PS4 won't be supporting DLNA, MP3, and audio CD support. In simpler terms, you won't be able to establish a media server to share video, audio, and image files across various devices. You can only acess music on the console using Sony's subscription based music streaming service Music Unlimited.
However, Worldwide Studios President Shuhei Yoshida acknowledged the public's frustration over the lack of these features and are forwarding it to the developers for future consideration. So, it's still possible that the PS4 will have these capabilities in a future patch.
This might not be a reason that can stand on its own, but it's definitely something worth considering.
