A lot of Windows 7 Eye Candy but is it enough?

This week saw the unveiling of a handful of early screenshots of Windows 7, the next-gen Microsoft Windows that should replace Windows Vista by 2010. My first reaction is that the new Windows looks beautiful, a significant jump towards an operating system that is actually enjoyable to use. But I'm sure that my initial reaction to Vista was the same thing, and a lot of what what was meant to be in Vista never happened. Additionally, much of Vista that exists is slow and unfriendly, so in the end it didn't turn out to be much of a revolutionary step for Microsoft Windows. At this point, another potentially false promise of a powerful Windows operating system probably won't keep me from finally purchasing a Mac as my next computer.
