I've been working through the beta version of your Rails 4 book for the past couple of weeks, and it's been an absolutely stellar experience. As an experienced front-end web developer, I've not had proper experience with TDD before, but your book emphasises it's important while keeping it relatively easy. Only rarely have I transcribed some code without really understanding why or what it's for, and I feel like I genuinely get how my application (thus far) works. My only concerns are with a few of the Rails conventions, which are probably due to my own conventions with JS and PHP. Thank you for your awesome work. I'll definitely be buying a copy asap.
