Differences between PS3 and PS4 besides graphics?

[Amelia_Pond_Behemoth]

You can easily switch from controller to keyboard and mouse. It was not so easy to play keyboard and mouse style via PS3.

I'm curious about this. On PS3, I just plug in a usb keyboard and I'm good to go. I always kept the keyboard right beside me. I assume PS4 still gives me this option, plus what you mentioned. Could you elaborate on that?
