Complete baloney.
It's all done according to Apple's design and specs. If it doesn't come from Samsung it'll come from someone else. Samsung is a major supplier, that's it.
Why is there no "retina" Samsung tablet??
No, I'll thank Apple for being Apple. That's the one and only reason I've got an iPad in my hands today and not a slab of crap that we saw pre-iPad.
No, it's not complete baloney. Yes, Apple determined the requirements and most likely designed / was responsible for the engineering of the retina display. But the fact is...YOU (as well as myself), do not know exactly what kind of collaboration between Apple and Samsung occurred to support the engineering of this display .
In addition to that, per your comment "If it doesn't come from Samsung it'll come from someone else"... if that's the case, then why isn't the new iPad being released with retina displays from other companies? Give credit where it's due. Being able to produce a display that meets retina specs and being able to do it in mass quantity with a certain level of quality does deserve recognition.
You do realize that it's possible to appreciate what Samsung and Apple both do, right? That appreciation isn't mutually exclusive.
