There's also a Laravel 4 book released today. It's Laravel: Code Bright (https://leanpub.com/codebright) by Dayle Rees, a member of the Laravel core team.
It's the featured book on the Leanpub homepage (https://leanpub.com/) right now, and it's doing really well.
Yeah, I forgot to mention https://leanpub.com/laravel-testing-decoded which is an oversight on my part! Laravel 4 is #1 and #2 on Leanpub for the past week, just because of today!
I really liked the static method shortcuts Laravel has for almost everything. Too bad it's almost as slow as Symfony, because it uses so many of it's (great) components.
Personally I like to follow coding standards when writing app in given framework, so I always start with looking at what they look like and I find that very often there is something that I personally find off e.g. in lavarels case they use tabs for indentation or classes have braces in the same line as class name, but not methods. Other than that project looks great!
