A new debate has ignited the web and the blogosphere after a journalist Philadelphia's City Paper weekly reported on a blog that Barack Obama was seen in a gym carrying a ..Zune.

As you might remember Zune is Microsoft’s response to Apple’s iPod, released two years ago and revamped with new models and firmware earlier this year.

In fact, the writer was reporting about his encounter with Barack Obama in a gym, but the Zune detail caught the bloggers’ attention and in a matter a minutes a new debate has ignited all over the Web: is Barack Obama a Zune guy? He is known as a Mac guy and as a BlackBerry user.

However, an Obama spokesperson was quick to clarify for The Wall Street Journal that the President-elect was carrying in fact an iPod and not a Zune. “Not true, the President-elect uses an iPod,” he said for The Wall Street Journal.   

In a clarification posted few hours later, Neal Santos from City Paper weekly noted that he definitely saw a “Zune in action”, but he admitted that the device could belong to one of the Secret Service guys who were protecting the President-elect.

Despite Microsoft’s efforts to promote its gadget, Zune remained a distant contender for Apple’s iPod, which currently dominates the MP3 players market with a 70 percent share.

But an official endorsement from Barack Obama could mean a lot for Zune. Unfortunately, it seems like the President-elect is an iPod guy after all.
