This IDC study looks at the worldwide and U.S. portable PC form factor market by commercial and consumer segments out to 2010. Seven subcategories are tracked and their shipments are estimated.

"Consumers are a growing force in the portable PC industry. With prices coming down, performance going up, and new features, such as increased wireless connectivity and widescreen displays, being embedded into the systems, consumers are being attracted to the portable market like never before. Also, their participation is adding to the pre-existing momentum of the commercial market, boosting prospects for the mobile market. Industry shipment trends are already demonstrating the shift." - Richard Shim, senior research analyst with IDC's Personal Computing team
