Sam Cece, president and CEO, StrongMail Systems

Based in Silicon Valley, California, I travel domestically or internationally at least twice a month. Besides my fully loaded Samsung BlackJack (Google Maps keeps me on track, no matter where I'm at) and Bose QuietComfort headphones on aeroplanes, I rely on social networking tools. LinkedIn is good for keeping tabs on business contacts, while Twitter and Yahoo Instant Messenger help me keep colleagues, friends and family up to date with my every move. OK, maybe not every move.
