What are the big differences between IntelliJ + Ruby Plugin vs RubyMine?
Being an owner of IntelliJ Idea Ultimate edition, and having installed the IntelliJ Ruby plug-in, I'm forced to wonder how different that experience is from using the RubyMine IDE.

I'm guessing they share a lot of code & features. What are the major differences?

If I'm jumping into the world of Ruby, should I buy the RubyMine IDE or just continue using IntelliJ + Ruby plug-in?
