Oliver Ahrens, Acer's senior VP and Europe president, has declared Microsoft's secretive Surface line of tablets doomed to failure. Specifically citing business focus issues and a change in core business principles, Ahrens urged Acer's primary software partner to focus on Windows 8 and pre-existing business arrangements instead of the potentially-risky product launch. "Microsoft is working with two dozen PC vendors worldwide, including the local guys, whereas Apple is alone, it can more or less do what it wants," Ahrens said when further questioned about potential problems with the tablet.
