Design Patterns in Ruby

I bought Design Patterns in Ruby a few days ago. I'm about halfway through it, though so far I've not encountered anything I would consider "new." In fact, if you're already familiar with Ruby, you can save a few bucks and pick up that Head First Design Patterns book you have laying on your bookshelf, and translate the Java bits into Ruby.
The one place that Design Patterns in Ruby does make me happy is its use of native Ruby features applied towards these design patterns. The author will implement a pattern, then incrementally improve it throughout the section.
Overall, it's an okay read, but one worth saving until you have an excess of money (i.e., don't go without eating for a week to scrounge together the $49.99).
