About the authors:

Marc A. Viredaz Marc A. Viredaz is a researcher at Hewlett-Packard Laboratories, with interests in handheld and mobile computing, hardware design, low-power systems and computer architecture. Marc received his PhD from the Swiss Federal Institute of Technology at Lausanne. He joined DEC's Western Research Laboratory (WRL) in October 1995, where he became one of the hardware designers of the Itsy pocket computer. DEC became part Compaq in 1998 and Compaq merged with HP in 2002. Marc is now part of the Mobile and Media Systems Lab, working on alternate ways of using handheld devices.

Deborah A. Wallach Deborah A. Wallach, formerly of HP Labs, is currently at Google's System Laboratory. After receiving her PhD from the Massachusetts Institute of Technology, she joined the Western Research Laboratory (WRL) of Digital Equipment Corporation, which later became part of Hewlett-Packard Labs. She was a key system software builder for the Itsy pocket computer. Her research interests include reducing energy consumption, operating systems, networks and mobile computing.
