Spending on IT services surged by nearly 22% in Slovakia in 2005, reaching almost $315 mln. Due to the depreciation of the US dollar, growth in local currency was lower but still impressive at 17.3%. HP, IBM, Siemens Program and System Engineering, and Siemens Business Services all held on to top 5 positions in 2005, with Soitron moving into fifth position. Together, the top 5 vendors expanded their market share from 30% of spending to nearly 35%. Moreover, the top 10 vendors increased their market share from just under 48% in 2004 to almost 57% in 2005, IDC says.
