I personally really like it. I don't believe it will simplify life of non iOS programmers, but I find it a big step forward. The syntax is very clean and flexible and the functional construct will make the code much compact and readable when we will get used to the new constructs (imho some experience with Haskell, or any other functional and typed language will be quite useful). And in principle it can revolutionise the way scripting works in OSX. From the few test I've done, when it will be stable it will be a fast nice replacement for many of my python, sh and ruby scripts. Moreover, I think that this can set the basis for a better and simpler concurrency model in iOS too. But we will see. The only thing I find disappointing and error prone is the different passing behavior between structs and classes, but I assume that we will get used to it.
