[1] The MacBook Air went first

[2] Windows Vista was cracked (hacked) on the last day of the contest

[3] Linux remained undefeated

Although several attendees tried to crack the Linux laptop, nobody could pull it off, said Terri Forslof, a manager of security response with TippingPoint. “I was surprised that it didn’t go,” she said.
