Erm, that's because it doesn't DO ANYTHING except gaming... They didn't bother to include media functionality / any new features.
I should hope they can get their games console to a complete stage where it can play games!!
Not true, PS4 has netflix, music unlimited, it hopefully will stream movies, and it also has BBC iplayer so it does do more then play games, but it is primarily a games console. Which, fancy that it does that quite well..
It also has motion with the camera and limited voice commands not that any PS4 owner cares for it.
Clearly, you want a powerful games machine, PS4, you want a media system that plays games xbox one.
Seems odd that last gen, Sony pushed the media functionality the most, but now have gone back to roots with PS4 whereas MS has gone with media..
