"IT spending remains on track to at least match the level of overall growth recorded in 2006, in spite of lingering concerns over the U.S. economy that have arisen in recent months. Worldwide growth has been boosted by continued robust conditions in the emerging markets of Latin America, Asia, Central and Eastern Europe, and the Middle East and Africa." — Stephen Minton, vice president, Worldwide IT Markets
