The Key — “Managed Diversity”

• On average, the cost of migration to a Windows 2000 workstation from Windows 9x/NT 4.0 will range from $1,500 to $3,500 per desktop

• Windows 9x and NT technologies will coexist in most enterprises through 2002, fulfilling separate needs.

• Through year-end 2001, as many as 90 percent of all organizations attempting a 100 percent pure NT technology migration at the desktop and mobile levels will fail and will end up with a mix of Windows 9x and NT technologies (0.9 probability).
