Some customers are considering whether to deploy Windows Vista or whether to skip in anticipation of Windows 7.
The discussion is often phrased as one of balancing costs and timing of releases. By not deploying Windows Vista, it means missing out on the proven benefts such as better security, productivity, search, mobility, manageability, and infrastructure optimization. Windows Vista works with more applications and devices than ever before and can be signifcantly less expensive to support than Windows XP SP3.
There is no need to wait for Windows 7. It is a goal of the Windows 7 release to minimize application compatibility for customers who have deployed Windows Vista since there was considerable kernel and device level innovation in Windows Vista. The Windows 7 release is expected to have only minor changes in these areas. Customers who are still using Windows XP when Windows 7 releases will have a similar application compatibility experience moving to Windows 7 as exists moving to Windows Vista from Windows XP.
Historically, mainstream deployment occurs not when Microsoft releases a product but 18 months later. While the mainstream deployment cycle is beginning for Windows Vista now, it isn't expected to begin for Windows 7 until at least mid-2011
