While meeting with a group of students, one of them asked the multi-billionaire: "Mr. Ballmer, would you sign my laptop?" The inquiry earned laughs from the group, as well as as the Microsoft executive. "It’s got Windows on it," the student said, "I promise."
"Oh yeah," Ballmer said sarcastically, before taking the MacBook Pro and signing it with a marker. The autograph came with a note: "Need a new one?"
"It’s all yours," Ballmer said as he handed the Apple machine back to the student.
The student also uploaded a photo of the signature to his personal Web site.
