Most of the comments here are way off base, focusing on the relative worth of the objective-c language, rather than the value of Eero for developers who have no choice but to use objective-c, regardless of how good they think it is or isn't.
If you haven't already - I highly recommend following the link. RubyMotion was somewhat interesting, but really didn't feel like a massive improvement over plain old objective-c, especially once you factor in all the Cocoa APIs.
However, Eero looks amazing. The syntax used represents a vast improvement over straight objective-c or RubyMotion. Take a look - it's genuinely exciting.
