Is async programmin so easy?

I am studing nodejs after a lot of work on Java Struts, a bit of cake php,rails and python django. All this web framework share similar ideas. But nodejs is different because of its asynchronous nature. Is it really /simpler/ to code in nodejs in respect of the other web frameworks? I dunno...but if I must set up a 8-guys project, I'd like to know the pitfalls :)
