Sam Francisco, among other places, is home to a new billboard from Microsoft, advertising, of all things, Excel. Actually, they are advertising the Surface and Surface 2. The selling point is that these devices come with Office, which comes with Excel. Trust me; it gets better.

Apple has done it again! They have created an ad that makes you think about technology in a whole, new way. Don't get me wrong. we've seen the pencil trick before, but never to this effect. Hiding things behind pencils is a way of demonstrating how thin it is. While it is true that the pencil is used as a visual prank to show how thin the iPad Air is, thinness and lightness of the device was not really the point. It is that bigger, more important point that I wish to address.
