Pardon my noobiness, but how is this different from a full fledged IDE like Netbeans or IntelliJ? For example on Netbeans you could have a good workflow similar to Yeoman. By using shortcuts you can push changes to your test instance, it has plenty of integration with Ant, Phing, Hudson/Jenkins, Github, other bunch of plugins, etc. It has a fully functional bash shell window, shortcuts that trigger the browser. You barely don't have to switch to anything while coding on it.

I get that IDEs like Netbeans have a bigger memory print, but what I mean is that using a tool container that gathers` all your other tools together is really nothing new.

Am I missing something here? What do you guys think? oh and I don't want to start a vi vs IDEs war here. I'm talking about the concept.
