Micron today started shipping a small ClientPro PC, the Cf. The 15-pound commercial PC features integrated components, saving on space and reducing cost but also limiting any future upgrades. "We're seeing a change in corporate buying away from investing in big boxes with lots of expandability," said Rob Meisner, director of ClientPro product marketing. "More is no longer always better." The base model comes with a 433-MHz Celeron processor, 4.3-GB hard drive, 15-inch monitor and Windows NT 4 for $999.
