I never really understood what people find so confusing about Android phones. Yes many have different a different skin over the OS with a slightly different UI, but in general, especially for non-power users, they are nearly the same as iOS. I also think that Android is more similar to a desktop environment that many people would be familiar with on a traditional PC, especially Mac users. You have a desktop with shortcuts and a drawer where all the apps actually are. Like it isn't that hard of a concept.
As for the Retina thing you just have to come up with a gimmicky name for something and people will say it is better without really understanding what it is.
