I remember when these types of threads used to pop up about the PS4 in its first two years. To those who feel the need to justify your purchase, the only person you need to justify to is yourself.
I think you guys are overreacting to this thread just a bit. It's not like he came out with a bunch of inflammatory statements sounding desperate to prove some childish point.
