I don't think it's about iPhone vs Droid bs Nexus: it's about phones and tablets versus desktops and laptops. Most laptops today aren't sold with a 200+ DPI screen. I think I'd have a hard time finding any. And yet, most phones (and tablets, with the new iPad) do have these high-density, better, screens. Jeff's point is that the switch to phones and tablets is what enabled that improvement to occur.
