Google buys Motorola. Denies any plans to do anything with it. No one believes them. Flash forward. Rumors spread Google is doing something with them. Deep breath. It's rumored to be an "X Phone" designed, once again, to take on the iPhone.
That might sound silly until you realize it's been Samsung, not Google, who's had all the success in the market against Apple. Now that Google owns Motorola, it only makes sense they'd want that division to be profitable as well, and to be an insurance policy against the power of manufacturers like Samsung, the same way Android was an insurance policy against the power of BlackBerry and Microsoft at first, and then very quickly Apple.
