You would have to never watch TV in order to not see the commercials about Mac Vs. PC  you know the ones where Mac talks about PC and how Mac is superior and now many restaurants like Pizza-Hut, Jack in the box, and Sonic are insulting the competition. I encourage you strongly not to do this when market your business. Focus on the good of your company and not the bad of others. If you do this then the consumer will figure out soon enough who is better.
