Sylvester Cann gone to meet President Barack Obama. He took his iPad with him written, "Mr President, sign my iPad" using Adobe Ideas app.
"At a rally in Seattle at the University of Washington, the President signed his autograph on my iPad using the Adobe Ideas app.
Generally, the President doesn't sign autographs along the ropeline because pens can be used as a weapon, so I thought I would try to hand him my iPad with a message on it saying, "Mr. President, sign my iPad".
He looked at it for a second and then used his left hand to sign.
It was kinda funny because he looked up and gave me a big grin afterwards as if he thought it was pretty cool too."
