IDC said it expects worldwide IT spending to grow 6.1% for 2005, a year that will be marked by enormous turbulence and significant consolidation and realignment in several key sectors. The 6.1% growth, a slight improvement over the 5% growth rate expected for 2004, means the IT market will exceed $1 trillion in overall spending, delivering about $60 bln worth of net spending growth, according to IDC executives.
