Just stop by the apartment of David and Juli Rasmussen. They are joined by a friend, fellow M.B.A. 2000 graduate Carla Huffman, 29.
Portable computers rest on their laps.
Carla and Juli play an on-line computer game. David, an Australian, is on-line, too, tuned to an Australian radio station that belts out music. He pulls out a digital camera and snaps a photo of a visitor, then loads the picture onto his computer and pastes it into the album. The doctor confirmed the Rasmussens diagnosis after the couple demanded that they be tested for giardia. Huffman says she uses her e-mail so much, and her phone so little, that she sometimes forgets to retrieve phone messages.
