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)?

.NET sucks because it is not really portable. Mono works, but not as well as Java. That said, the .NET library is clearly superior to the Java library. For one thing, it's not self-obsessed (i.e. no "MSButton"s in .NET, unlike Java/Swing/whatever's "JButton"s).

However, if you're just doing Windows programming, then .NET is the clear way to go, unless you NEED the program to run on a vanilla Windows XP install with no internet connection.
