This is the best presentation I've ever seen come out of MSFT! Congrats. As a fresh CS grad, I've heard academic whispering about functional programming but have never had the opportunity nor took the initiative to dig any deeper and learn it for myself. I'm excited that a pragmatic, .NET interoperable, first-class functional language is on the way from Microsoft. Great work guys! After 20-odd years following the computer industry I've never been happier with Microsoft. F# (and Oslo) show that Microsoft is not being complacent. And after Apple's all-style-no-substance "I'm a Mac; I'm a PC" campaign I even find myself rooting for MSFT. But I'm rambling in short great work on F# and a great introductory presentation with a sprinkling of humour Smiley.
