That's ultimately my impression as well. At the end of the day, whether it's Ruby or Objective-C, you're spending the bulk of your time in Cocoa so switching to Ruby doesn't buy you much.
It buys you an enormous "much". I've never built an iOS app so quickly in my life, and my god --should I say anything about code-readability?
