Windows still No. 1 in server operating systems
According to IDC’s data, Windows is still the dominant player. The fourth quarter 2009 was more robust than the third, in terms of total revenues and units. Windows’ share of the total stayed constant unit-wise, yet declined, dollar-wise, when compared to the previous calendar quarter.
That said, Windows is still far and away the No. 1 server operating system, in terms of units, and the definite leader in terms of dollars.
