what to do now?

Nothing really.

Best bet would be to post in Xbox Forums and Gaming Forums about how you're enjoying it (lie if you have to like most people). Next buy a few hundred dollars worth of games that you normally wouldn't play, but since they are either exclusive or the only games out you feel obligated to play them. Make sure one of those games is infamous so that you can take screen shots of it and post them saying it looks better than most PC games for mad trollz and lolz. Next once you're bored of the games you got (This should really only take 1-2 hours depending on how long you force yourself to play them) download an app like netflix and use that. Remember! You don't have to pay for PlayStation+ to use netflix so it's kind of a "must have" thing to do! Congrats that's the basic rundown you can expect a lair of dust within the next few months to complete this transition and process. Good luck and have fun :^)

I'm feeling some tension here

On a more serious note, currently there truly isn't much to be done with a PS4. I've been playing indies for the past months, and it gets pretty fucking boring. Thankfully, great games will become available around September - October and from there it'll just keep on flowing.

Here's a little preview of what you can expect :

09/09/2014 Destiny
07/10/2014 Driveclub
07/10/2014 Dragon Age: Inquisition
07/10/2014 Middle-earth: Shadow of Mordor
28/10/2014 Assassin's Creed : Unity
11/11/2014 The Crew
18/11/2014 Farcry 4
20/02/2015 The Order: 1886
24/02/2015 The Witcher 3
31/03/2015 Bloodborne
31/03/2015 LittleBigPlanet 3
2015 Uncharted
2015 The Division

These are the games I will most likely jump on, there will definitely be other worthy ones.

Was going to write one up for the Xbox section too, but got called into gaming.
