Almost a quarter of the world's population -- roughly 1.4 billion people -- will use the Internet regularly in 2008. This number is expected to surpass 1.9 billion unique users, or 30 percent of the world's population, in 2012, according to IDC's Digital Marketplace Model and Forecast.

"The Internet will have added its second billion users over a span of about eight years, a testament to both its universal appeal and its availability", said John Gantz, chief research officer at IDC. "In this time, the Internet has also become more deeply integrated into the fabric of many users' personal and professional lives, enabling them to work, play, and socialize anytime from anywhere. These trends will accelerate as the number of mobile users continues to soar and the Internet becomes truly ubiquitous."

Worldwide PC shipments are on track to reach 297 million units in 2008, a 12.5 percent increase from 2007 shipments of 264 million units, according to Gartner. The company's analysts have increased their outlook from their previous forecast due to the continued strength in mobile PC growth. In March, analysts had projected an increase of 10.9 percent.

"Mobile PC shipments exceeded our expectations in the first quarter of 2008," said George Shiffler, research director at Gartner. "Mobile PCs continue to have strong momentum and the global economic environment is proving to be less punishing than we expected. Even so, it's a bit premature to say PC shipments won't be impacted by a weaker global economy, especially if oil and food prices continue to soar."
