Personally, I think saying we have a "Pixel Qi" display is more
impressive, but of course, that does not have the name recognition of
"retina" given the amount of marketing dollars on the "retina"
branding by Apple.  Any question on characterizing the display should
probably be referred to Mary Lou Jepson (now at Pixel Qi).

IANAL, but the term "Retina" in reference to computers and mobile
devices is an Apple trademark, so any such use (referring to anything
but an Apple device) would be violating their rights to that mark.
