What are the advantages / limitations of MacRuby and has anyone used it to program on an iPhone?

I continue to use MacRuby links and wondered if any of them used iPhone / Objective C for programming.

The MacRuby website says: "The goal of MacRuby is to create full-fledged Mac OS X applications that do not sacrifice performance in order to take advantage of using Ruby."

So my question is: what are the benefits of Ruby?

And, more importantly, what are the limitations?

You will never run it on an iPhone unless Apple decides to remove restrictions on the absence of background processes currently imposed, so if you are interested, don’t worry.
