Simply put: So far SONY has done everything right..and by everything I mean everything.
When the only complaint I can come up with is that the blue controller LED could be somewhat annoying..well, then they really did a great job.
Not that I'm entirely convinced that everything will be as great as they make it sound.
But compared to the clusterfuck that was the PS3 (imho) they really did an impressive job making me want to buy a PS4 (If I buy a next gen console)
