Oh, and I'm a proud Windows XP user, no fanboyism inside :)
Anybody that's not looking at Linus (for a second time, if you were around for the beginning of Linux, or for the first time) with a sense of wide-eyed amazement just isn't paying attention. He's now helped reinvent two entire industries. git is pretty revolutionary...it builds on the shoulders of giants, just like Linux did previously, but it makes the leap that no one else as made and puts it into a simple package (Mercurial and darcs and bazaar all come close, of course, but all have a "research project" feel to them in several important areas--partly because git came last in the line and could learn from their mistakes, but the same is true of almost every great idea).
If you read the kernel mailing list, there is sometimes the question of "what happens if Linus gets hit by a bus?" He always says that it shouldn't adversely affect development... :)
