F#

So anyway I have begun my foray into F#.  Because I plan to use .net in my next project I think it will be fun to learn F# in addition to C# and use both languges in the project.  To this end I just ordered Expert F#.  Knowing /prog/ is infinitely more expert then me: 

what does /prog/ think about .net?
what does /prog/ think about F# (ocaml)?
What type of tasks are better to be performed in F# vs C# (Math type tasks heavy)?

Oh, yes, the Mac OS X support is just so great.

The current version of SSCLI is 2.0, which contains most of the classes and features of version 2.0 of the .NET Framework. Unlike the previous version however, it is only supported on Windows XP SP2.

Microsoft is not committed to portability in the same way Sun is. If Microsoft had really cared to fully port .NET to OS X and/or Linux, then it may have had a really good chance of displacing Java.
