Great F# tutorial

Looking for *a good F# tutorial *to figure out what the hype is all about? Check out the excellent F# series on Kevin Hazzard's blog. Maybe a little out-dated when you're using the September 2008 CTP of F# (there's no add-in anymore, and the command mentioned in part 2 has a different name - just search for 'send'), but finally a tutorial that explains it step by step.
