Worldwide IT spending in 2010 will jump to $3.4 trillion, and could reach more than $3.5 trillion in 2011, according to Gartner. Helping to drive the upward trend are consumer mobile PCs, virtualization and security software, Gartner said.

IT spending worldwide should grow 5.3 percent in 2010 over last year, reaching $3.4 trillion, according to industry research firm Gartner.

In addition, spending will continue to increase into 2011, growing 4.2 percent on sales of more than $3.5 trillion, Gartner said in a report April 12.
