In the news: Yesterday Obama, after meeting with Steve Jobs and Google exec Marissa Mayer's house for dinner, he decided to give autographs at iPad like celebrity.
Sylvester Cann IV holding iPad in shots, used the Adobe Idea app to scrawl his request to Obama, "Mr. President, sign my iPad." Even without a "please" or "thank-you," so this is what Obama did as you can see in shots below.
If you compare the signature on the iPad to his usual signature, it looks more like a 10 year old's attempt at forgery, but nonetheless Sylvester is a damn lucky guy to have that image in his possession.
But i think Sylvester has published that at his site
