So, your saying buy a PS4 for 400+ bucks to use my cellphone because they can't even supply basic communication to friends I don't even know in real life yet have in my cell phone. Buy a USB keyboard but yet it's still going to block my main screen view and cost me extra. Btw not everyone has a cell phone.
-Instant messaging is a must with touchscreen keyboard
-Mailbox system just needs to be organized more
Overal rehaul and organzation of social connection to my friends. make it easir, make it simple and make it work. If your fine with these features keep the PS3 and stop downing everything I said when the PS4 should have all of these features and more
