I've seen this comment posted on other sites too... Why is it funny?
That is a Microsoft "business" solutions page. Last I checked, Microsoft provided business and productivity software for Apple products as well. After all, one of the biggest announcements of the OSX 10.6 is that it has native MS Exchange support.
Perhaps instead, Microsoft intends to show that not only do the support the Apple products, but also interoperability with existing Windows PC platforms. Of course that is assuming that the generic (Dell) monitor is supposed to be plugged in to a Windows PC computer. It could just as easily also be connected to an Apple PC. Of course... what really happened is that the company was too cheap to buy a splitter or two sets of cables for the projector that is on the table. So, they had to disconnect the power and VGA cable from the monitor in order to display the output for the entire room. That is why she is straining so hard to see the screen at the front of the room.
