THAT is a Dev phone. It is the BB10 Dev Alpha A It's very basic. Has most of the phone features locked out. but has very good spec so does enough for developers to be able to use them during app creation. They were never sold to the public, only a BB dev could get one. This is a classic example of developer hardware.
The Nexus 4 is available in Google's play store which every Tom Dick and Harry can access and buy from. Nowhere is it aimed at Devs, but is sold to the mass consumer on a site on which you erm....consume content. See a pattern developing here? It;s quite a clear distinction, using the BB example and the Nexus 4 that one is available to Devs exclusively, the other is a mass produced consumer focused smart phone sold to Joe Public for a very reasonable price.
End of Argument
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
