Gartner recently published a detailed report on their perspective for IT Spending. You can get the detailed report here. I was particularly interested in the forecast around IT Services and here is some text around that from the report.
Worldwide IT services spending is on pace to total $781 billion in 2009, a 3.5 percent decline from 2008. In 2010, worldwide IT services spending is forecast to reach $816 billion, a 4.5 percent increase from 2009 (see Table 5).
