Microsoft and ASUS on Friday ramped up a video ad campaign (below) to steer possible iPad 2 converts towards the Eee Slate. The four spots all focus on one person's use case, such an artist, a blogger, a business owner, or a mother, to show how the Windows 7 tablet helped them out. Each of them is consciously aimed at those who might consider Apple and show either an area Microsoft believed it had an edge, like Office support, or directly attack a perceived iPad flaw.
