(Telecompaper) Worldwide IT spending is projected to total USD 3.7 trillion this year, a 2 percent increase from 2012 spending of USD 3.6 trillion, according to a study by Gartner. Last quarter, the researcher's forecast for IT spending growth in US dollars was 4.1 percent. The 2.1 percentage point reduction mainly reflects the impact of recent fluctuations in US dollar exchange rates; growth in constant currency is forecast at 3.5 percent for this year, down only slightly from last quarter. The forecast for spending on devices has been revised down from 7.9 percent growth in Gartner's previous forecast to 2.8 percent. The decline in PC sales recorded in the first quarter continued into the second quarter with little recovery expected during the second half of this year.
