Obama is an iPod user and someone lent him a Zune. Shame, that was not was not spotted before Slashdot was used as another Wintel advertisement vehicle for the very failed Zune players. Knowing M$, they had W.E. slip him one so they could splash the story around for Christmas. Sorry, Steve, it won't work.
People looking for a music player should buy a used iPod and install Rockbox. You keep good quality hardware out of a landfill and get software freedom for a better price than a Zune that way.
