Let's face it, the president is not cool. C'mon, he still uses a Blackberry. He would move to Apple, except that Steve Jobs insulted him by making Barack personally call to make the appointment and then Jobs told him to cut out the crap. And Barry can't go to Android because they are just not cool, not at all, way too common for the enlightened. So his personal grudge against Jobs and his vanity wins out and he still uses a Blackberry.
