Installing is fantastic on the PS4.
Yesterday I had to delete my Assassin's Creed 4 game data to see if the install was causing my graphical errors (It was my HDMI port on the TV...).
I was great that it took all of 3 seconds to delete it all and then only ~30 seconds to install to the point where I could boot the game back up again.
iPhone = Great gaming device. Don't agree? Who cares, because you're wrong.
