Displaymate's Raymond Soneira agrees with a Tim Cook. But I suppose critics will argue he has an agenda or is a pro-Apple fanboy.

Not sure why people care what Cook says. And as others pointed out its not like Samsung hasn't done their fair share of cheap shots. I haven't seen any Apple commercials out there making fun of Samsung customers or knocking their mobile phone displays.
Have you seen the CEO of Samsung trash Apple? That is the difference.
Ads are ads... and Apple has certainly been guilty of that too ("I'm a mac")
