Google Inc will soon unveil a tablet co-branded with Taiwan’s Asustek Computer Inc and priced to compete with Amazon’s Kindle Fire device, an Asustek executive said on Wednesday. Amazon’s Kindle Fire, which runs a version of Google’s Android operating system, sells for $199. Through it users can access Amazon content including books, music and video. “It’s targeting Amazon. The Kindle is based on Google’s platform but with its own service, so Google has to launch its own service, too,” said the executive of the device.
