Congrats. I still can't get by the initial cost of RubyMotion. I know, it will pay for itself, but that's a lot of initial buy-in going on faith. I wish they had a demo version available to try before buying.
I'm in the same boat. I WANT to try it, I WANT to love it, but I can't justify paying for it just to find this out, especially given that I already know the Obj-C ways of iOS dev.
