[citation][nom]Rantoc[/nom]2560x1600 have a proper name already - WQXGA. Retina is just crapples way of saying to the sheeps that its something "cewl" and a must have although i bet the eyes cant actually distinguish pixels at that res and tiny screen size.[/citation]Yeah... because I'd totally rather use the awkward and difficult to remember WQXGA acronym than to just say "Retina". Not to mention, the term Retina has nothing to do with that particular resolution but with achieving a pixel density where the human eye is unable to resolve the individual pixels that comprise the image at the distance the screen is to be viewed from.
Oh, and the iPhone's screen definitely looks better than displays with lower pixel densities, so you lose your bet.
I have no particular love for Apple, but this weird backlash against the term Retina is dumb, especially from people who, apparently, don't even know what it means. Yeah, it's a marketing term, but it turned out to be a useful one.
