I think I'd miss pattern matching the most. The first time I saw how pattern matching with regular expressions automatically extracted the matching bits I was sold. I'd also miss block expressions. I keep wanting to write if-expressions (as opposed to if-statements) in every non-scala language I touch. But I agree, c#/.net is a good alternative if you're used to the expressiveness of scala.
