Comparing Vista to ME is like a bologna-eating contest. Neither tastes particularly good and we know where both are going to end up.

Windows ME had no product activation, was completely buggy, and had very little to offer in terms of new features. System Restore, a new interface similar to Windows 2000, and Automatic Update were about it. It was a fair operating system, though, as it took as long to shut down as it did to boot up. Since Microsoft decided to remove non-PnP drivers from the installation CD, it had compatibility issues with software, was tricky to install, and tough to get legacy hardware running. Because of this, Windows ME made the number 4 spot on PC World's "25 Worst Tech Products of All Times" list, a distinction no one would want.
