10.) Cross-game chat
Cross-game chat in the PS3 never happened, but it finally arrived in the PS4 and players couldn't be more pleased. Your voice chat won't be disrupted regardless of what application you are using and even if you are constantly switching.
It was cool how I could also do voice chat without having the camera. If I remember correctly, the PS3 would always ask me for a camera when I attempted to do it. The app is also a great complement to the chat because you can now talk to your PSN friends wherever you are. No need to add them in an external platform if you don't want to.
