President-elect uses Microsoft Zune

Barack Obama has been revealed as a Microsoft Zune user, according to new reports online.

The president-elect of the US was spotting using the mp3 player while working out at a gym in Philadelphia recently.

According to the Philadelphia City Paper’s Neal Santos, who was exercising at the same location, Mr Obama listened to tunes on the device and read a newspaper while running on a treadmill.

He wrote a blog: "I did a double take, and soon after that, looked around the gym to see if anyone else knew he was here. Nobody seemed to notice.

"But he hopped on the machine next to me and broke a mean sweat while reading a copy of USA Today and listening to his Zune."

Earlier this year, Microsoft launched two new 16GB and 120GB versions of its Zune mp3 players.

The systems also include a new feature which allows users to buy songs that they enjoy listening to on the devices’ built-in radio tuner.
