It's good and it can be impressive for average consumers, but I really doubt it's impressive for most GAF.
A lot of people on GAF are console gamers and will greatly appreciate the ability to multitask on the console itself. Myself included. It doesn't matter if other things did it first, if you love console gaming the ability for consoles to multi task is great news.
I just hope PS4 gets Skype with text chat. I know they said they're not completely closed to the idea despite being owned by MS now.
