iPad signing? Probably. One Sylvester Cann attended a recent rally in Seattle at the University of Washington, and was somehow fortunate enough to get within eyeshot of Barack Obama. According to Cann, the secret service wasn't exactly sure about the Prez handing over his John Hancock on a tablet, but eventually they cut loose and let him autograph the tablet with his finger using the Adobe Ideas app. There's a video just below for those who are still in disbelief, and we have to say -- that autograph ain't half bad for using one's digit to create it.
