It would have been over a year ago. I am not interested in using it, I was just curious about it at the time. (I don't really get along well with anything that expects me to use a mouse.)

I sorta doubt that the emacs/vim support is anything near what there is for OCaml, but knowing Xamarin it will get there... eventually. But really, I don't see a big reason to pick F# over OCaml unless you're already doing .Net or something.
