Even for a normal person, leaving your BlackBerry at home is a pretty traumatic experience that results in panic and ultimately a return trip home but if you're President Barack Obama, that experience is even more intense. As he was heading to Las Vegas aboard Marine One, President Barack Obama realized he had forgot something in the White House and headed back inside, telling reporters 'I forgot something.'
As he returned back to Marine One, he said: 'Didn't you guys ever forget something? When reporters inquired what he had forgot, the long time BlackBerry user held up his phone. 'My BlackBerry,' he said as he got back on Marine One. President Obama's BlackBerry usage hasn't been any secret, but he's among many world leaders who also turn to BlackBerry to run the world. UK Prime Minister David Cameron, Canadian Prime Minister Stephen Harper, German Chancellor Angela Merkel and Danish Prime Minister Helle Thorning-Schmidt are among the world leaders who are known to use BlackBerry devices.
