As I remarked earlier Android is an open development platform. The reference platform i.e. the Nexus line has been given away to developers at I/O. Do other platforms do this - well no they dont, but you dont go from nothing to being the number 1 platform without developer support.
The only distinction being made here is you dont know what a reference model is. Each Nexus line has been made available to the public, they may not have sold well but they were available.
You seem to be posing questions rather answering simple queries I have made. How do you test a quad core phone on a dual core chip - please dont go their with emulation?
Are you saying people werent able to buy a Nexus One etc
By end of argument I assume you are conceding the point
I don't know about the previous nexus phones, were they pushed through contract market which is squarely consumer driven.
