Analysts believe businesses won't rush to update their computers to Vista. Instead, it's expect they'll wait about a half year to make sure the transition goes smooth and to be sure that they won't run into any nasty bugs.
It's not sure how fast consumers will adopt Windows Vista. The transition from Windows 3.x to Windows 95 went pretty fast, the switch to Windows 98 also went pretty quick but analysts say the transition to Windows 2000 and Windows XP went noticeably slower.
Windows Vista features dozens of new features, including much better security and a revamped user interface, and Microsoft really has a lot at stake with the launch of this new operating system. If enough PC users make the jump to Windows Vista, Microsoft's stock may continue to rally. Analysts report every 2 percent extra penetration will likely boost Microsoft's profits with more than 2 percent.
The software giant also released Office 2007 today for businesses.
