I used my PS4 for Blu-Ray last night and it was awful for integration into the OS, it looks as if it's been tacked on. If someone messages you, you cannot pause the film and reply back, you need to actually exit the film, whereas in a game you can pause it, go to the main screen and reply then jump straight back into your game again.
So when I did this last night I had to then re-set up the film (I use specific audio settings for SQ) and then go to scene selection to find where I roughly was and then start from there. Should I get another message in future I will simply have to ignore it, which begs the question why even show a pop up on screen that someone has sent you an invite or message when you cannot go into them without exiting the film?
Another thing that I don't get is people spend £600+ easily on a console (when you add in online sub costs (£40 a year), game costs (£40+ each) and additional controllers (£49 each) or headsets (£50-£200), etc).
Yet then use a crappy £300-£400 tv to play it on.
My GT50 only cost £799 iirc (50 inch top end Panasonic plasma panel) and has DLNA built into it. I then use my Nexus 5 or Nexus 7 with bubbleupnp to stream anything I want directly from my phone to the tv (tv shows and movies) or I can put it onto USB from the PC and put the USB straight into the TV and it will play most files no bother without additional hardware so I don't need a media centre or anything as the TV can do it all for me. It also has 3D, came with 2 sets of free glasses, 5 year warranty, Smart TV, gaming mode (low input lagg), etc, etc basically tons of stuff.
Because spending less on a mediocre tv then having to buy additional stuff like WD live's and USB hard drives or network drives work's out to slightly less cost wise, but then you have to live with a much smaller and lower PQ panel for the life of the TV.
Why not spend slightly more in the first place get a top end set and then you don't need to buy little things to add onto it? You will also have a much better tv which is far more important because you use that for everything, TV, Movies, Consoles, etc.
IMO if you can afford to spend £600+ on a console you should be buying decent TV's to play them on which do everything without additional stuff.
