Yesterday, Google introduced its long-awaited touch-screen phone, called the Nexus One. This long-awaited new device/announcement is driving some chatter about the future of the Mobile OS world. Much of the chatter is around pricing (to carriers), revenue model, and market share. Google is effectively paying carriers to sell it's phone (platform) with the intent to generate revenues from search down the road. That's a substantially different approach than Apple took with the iPhone.
