Okay, let’s make this clear: The Nexus is just another Android phone.
However, it’s one that Google have thrown the full weight of their marketing effort behind. Bear in mind these guys don’t hold press events for the opening of every envelope- the last big one announced Google Wave and that was only as part of a larger Google I/O gathering.
Furthermore, Google are notorious long-game thinkers. They gradually manoeuvre their way around the industry, insidiously implanting the importance of their products into your everyday lifestyle. It’s viral.
