Windows Vista is scheduled for consumer availability in six days. However, the latest operating system from Microsoft will have to displace Windows XP from its dominant position on the market. This because Windows Vista's main rival is not Mac OS, or Mac Intel or Linux. Microsoft's own Windows XP is the sole factor that stands before Windows Vista and the lion's share of the operating system market.
In this context, analyst Gartner has forecasted that Vista will not become the dominant presence on the OS market until 2009. In fact, in the first month of availability, Microsoft's Software Assurance customers failed to acquire Windows Vista via volume licensing, at a rate that would overshadow Windows XP's market performances.
Additionally, Gartner predicted that Windows Vista will only find its way onto 12.3% of the worldwide desktops. Windows XP, currently accounting for a share of 85.3% of the OS market, is also expected to diminish its dominance.
