Darn. I bought Crafting Rails Applications in paperback three months ago :( On another note, I've been using Rails4 beta and RCs at home for the past couple months and it has been a joy. At work I've also been working on a Rails 3.2 app and incorporating routing_concerns and strong_parameter gems. I think upgrading from Rails 3 to 4 apps won't be as drastic as upgrading from Rails 2.x to 3 apps was (curse you asset pipeline!)
