Windows 7 is more than just spin. It's stable, smooth, and highly polished, introducing new graphical features, a new taskbar that can compete handily with the Mac OS X dock, and device management and security enhancements that make it both easier to use and safer. Importantly, it won't require the hardware upgrades that Vista demanded, partially because the hardware has caught up, and partially because Microsoft has gone to great lengths to make Windows 7 accessible to as many people as possible.

It's important to note that the public testing process for Windows 7 involved one limited-availability beta and one release candidate, and constituted what some have called the largest shareware trial period ever. As buggy and irritating as Vista was, Windows 7 isn't. Instead, it's the successor to Windows XP that Microsoft wishes Vista had been, and finally places it on competitive footing with other major operating systems like OS X and Linux.
