STMicroelectronics’ touch controller provides the interface chip between the Alps-manufactured resistive-and-capacitive touchpad. Despite finally shipping product, the OLPC effort hasn’t gone flawlessly. Delays and cost overruns, along with a host of political hot potatoes, have given the project some black eyes. The current price tag for the laptop has ballooned from the original $100 objective to almost twice that, and our cost estimates—available in a more detailed report from Portelligent—show the reasons why. In short, displays, batteries, CPUs, fancy enclosures and the rest add up to a bill of materials that sits uncomfortably far from the $100 target. Can more widely available con- nected computing help bring countries from “developing” to “developed”? Only time will tell, but if nothing else, the OLPC effort helps change the way the industry thinks about how expensive a PC really needs to be. An acceleration of cost-reduction pressures for the larger notebook industry may be OLPC’s biggest impact, at least outside the developing nations targeted by the design. ■ June 23, 2008 | Electronic Engineering Times, TechOnline 55 http://www.techonline.com http://www.eetimes.com
