Why do they mention that and fail to mention devices which present even higher density displays? My Nexus 5 has 445ppi display density.
I find it annoying that despite the existence of common devices which are "better" that the "best" is still considered to be Apple's. Nothing like product endorsement which wasn't [likely] even paid for. At the very least, they should have included the trademark sign to indicate they were making a commercial reference in their endorsement. (They did, at least capitalize "retina" in retina display... that's not quite the same thing and kind of makes it worse.)
