You should go to his page and see why his hair is that way. Its a tribute to his Mom. He is right, in todays time we have so many avenues to complain that we blow things out of proportion. Test charts, thats one thing and I can see a need. But like he mentions here a dead pixels at HI ISO, I mean really. The issues to me with the D600 are a real issue, the issue with dead pixels at higher than normal ISO is stupid to even complain about. I am sure the left focus with the D800 may be or was an issue, not familiar, only read a few things about it. You know its the same thing as with any other electronics you buy, the Iphone had issues, Laptops have issues, TV's have issues. Go to the source and not the street to get things resolved and make sure its a real issue before you do take to the forums and bitch about it.
I really like this guy, I have learned a lot from him and his videos since I got back into DSLR's. I even refer new people to his YouTube stuff. As well as this forum.
Here you go.
