Windows Server 2003 Editions Compared

Sure, Microsoft has its own table comparing the various Windows Server 2003 editions, but that version is incomplete, hard to read, and poorly organized, especially if you're interested in the features that are specific to the 64-bit editions of this product family. So here is my own comparative table, which I think you'll find to be much more readable.
