Microsoft Features and Releases Timeline?

maggard writes "Does anyome have any good timelines for MS Windows releases, their original feature-sets & what they eventually shipped with? MS has a long habit of promising lots of features in future operating systems, mapping out elaborate plans with dates & product codenames, etc. then, er, well it not quite happening. I'm looking to track some of these plans and match them up against what really shipped and when. I'm also looking to track all of the various Win-flavors out there now (something like a dozen or so) to point out that Unix isn't the only thing out there in danger of fragmenting."
