However, all that may be set to change with the news that the defence agencies of key Western governments such as Australia, the US, Britain, Canada and New Zealand have banned Lenovo gear from being used in sensitive areas, because of concerns that the Chinese vendor has been leaving back doors in its devices for the Chinese Government. No evidence has yet been presented to back the claims, but Lenovo remains locked out of sensitive areas of these governments. Is it fearmongering? Or is there some legitimate basis for the ban?"
