iMc: Persuasion and word elements

Did anyone else notice that two of the most established brands, McDonalds and Apple, both use a recognizable element in their product names? Mc/Mac for the former i.e. McChicken, Big Mac, and a lowercase i for the latter i.e. iPhone. What I'm most impressed about is that they get people to actually call these products by the name they've given them; they're not having breakfast out, they're eating a McMuffin. You don't just have an MP3-player, you have an iPod. (I've even heard people call Samsung mp3-players "iPods" but those people were all old.)
