Both Xperia S and HTC Rezound had 342 PPI, and were launched a long time ago: http://www.gsmarena.com/sony_xperia_s-4369.php http://www.gsmarena.com/htc_rezound-4099.php And bragging about having 3 more PPI than the iPhone is just lame...just as bragging about having "better than HD" display because you have 48 extra pixels, is.
Agreed. Not a lot to brag about, but I'd at least mention that it is retina.
Do we really need a term for "high PPI"? If iPhone 4 is retina, then what is Xperia S? It is certainly not retina, because it would be insulting to call it retina when its pixels are even more indistinguishable. What about Galaxy Nexus? It is 316 PPI, slightly less than iPhone. Is it enough for being retina or not? Who determines?
