Parts of this ad campaign were also made on Macs, and you can see those reports popping up everywhere, but it is false advertisement for Microsoft to portray people that use only Macs as using PCs.
Hey it is what it is. They hired a advertising firm to make the commercials. If they use Macs, hey they use Macs! BTW, doesn't the Apple retail stores checkout use a Windows based hand held device to process your credit card purchases? Call it a full circle. Sorry if this has already been discussed.
