Watch as HTC and Samsung run for cover with Windows 7 phone. No they didn't spend 12.5 billion for just patents and to play nice with their own smartphone manufacturing unit. While I'm sure Google wants HTC and Samsung to continue to make Android smartphone, you can bet they will be favoring their own brand.
