More than a billion PCs will be in use by the end of 2008, according to a worldwide PC adoption forecast by market research firm, Forrester Research.

The report also predicts that more than 2 billion PCs will be in use by 2015. The developing Russia, India, China and Brazil markets will account for more than 775 million new PCs by this time. Forrester Research states that it took over a quarter of a century to reach the first billion users but due to technological advances, lower prices and global demand for technology it will only take seven years to reach the next billion.

Simon Yates, vice president and research director at Forrester Research, believes that some of the main driving forces behind this growth include the One Laptop per Child (OLPC) and Intel World Ahead Program, which have targeted previously untapped markets. It does however foresee that PC technology suppliers will face a challenge to scale production with enough volume to drive down prices and meet affordability requirements.
