This is definitely an 'aww' moment and one that signifies that in the end, we're all just people belonging to the same world. In its latest holiday ad, Microsoft shows its retail employees form a beeline for the Apple Store in 5th Avenue where they serenade Apple Store specialists and customers by singing "Let there be Peace on Earth." At the end of this moving rendition, we see Apple peeps and Microsoft peeps break ranks to greet and hug each other while business in both flagship stores supposedly grinds to a halt. This is great ad with a great message at a time that needs it the most.
