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)?

Ah, primitives. Yeah, boxing sucks. If you want performance for the things you described in Java, you use an array unless you need a more advanced collection.
In your specific example it sounds more likely that the items in the list would be objects, in which case .NET generics will use code sharing too.
