Michael was going to DIE without an XboxOne, so we bought it shortly after the move. It has been nothing but issues. I'm about ready to throw it out the window or make him sell it. We're currently only using it to watch Netflix, and it can't even do that right. He's stopped playing his games on it because the servers kept being down for maintenance. Get your butts in to gear, Microsoft, or we're going Sony.
In short, at this moment, you aren't missing out on anything the new systems have to offer. I love my PS3 and am still getting a ton of use out of it, I don't feel the need for a new system yet.
(Course, I think the only console we don't have is a PS4 or any of the Wiis. Lol And I may be getting a used Wii from a friend's sister, because, Mario kart. And Smash Brothers.)
