Rob Bernshteyn, the CEO of e-procurement company Coupa, carries a MacBook Pro at all times when hitting the road. On the right, that's an original T-Mobile Droid phone and a Plantronics headset for Skype calls; on the left, an Itronics adapter for international power outlets, along with a USB drive. He also carries cans of Red Bull, packs of seaweed, and a boatload of business cards.
