Pff only noobs game on laptops. As far as the six axis goes, there have never really bean any legitimate uses for it. Best you could maybe say was Ninja Giaden 3's "funny" use for it. Regardless of that I have a bluetooth for my computer so if I wanted to I could use it. And the camera is not really gonna have any practical uses aside from kiddie games.
Also the PS4 isn't backwards compatable, but guess what my comp is. I can play PS1 and PS2 games on it and I bet I could find a PS3 emulator if I wanted to.
PCs are for LOLcats
