The Nexus One costs about the same as the iPhone to produce, yet the unlocked version is sold by the the same price that what an unlocked iPhone would be. That means their are getting Apple like obscene margins.
The point: You missed it.
The Nexus One is officially unlocked, and usable on just about any carrier. The carriers are the problem here, and breaking the hold they have over consumers in order to allow competition on price and quality is the goal. The Nexus One isn't magic. It doesn't fix the carriers; but it is one more thing to allow consumers to escape without having to break the EULA, hack their phone, possibly bricking it, etc. Apple is the enemy of this idea, not a friend, and the iPhone is among the best servants the old guard (well, the oldest guard, AT&T, anyway) has in their fight to maintain a stranglehold over consumers communications.
