Ask HN: So what are the early opinions on RubyMotion?

All the news seems to have died out in the last few days.

Has anyone tried it out? What problems have you run into? Is it worth the £100 as a hobby project?

I'm currently considering building an iOS application to supplement my website but it'd be my first step onto the platform. As a pretty experienced Ruby developer it looks like it might split the learning curve; learn the framework first, then Objective-C later.
