> I felt pleasantly surprised and never felt like there was anything bad about the language itself.

After working full time with F# for nearly two years I can attest to this. At worst there's inconvenient things, and as you get deeper into FP you'll wish F# had certain features, but all in all it's an very sane and well designed language. I think the only thing that's caused me any pain is the lack of type classes, and after doing a lot of MVU I wish lenses were a language level feature.
