What Does This Mean for NetBeans?

NetBeans has always been something of a mystery to me. I'd always regarded it as the runner-up IDE for Java, after Eclipse. But it's clear that I'm behind the times:

Netbeans 6.1 will have plugin support for creating, editing, deploying to Apache HTTPD, running and even debugging PHP projects.

And according to the NetBeans site:

You get all the tools you need to create professional desktop, enterprise, web and mobile applications, in Java, C/C++ and even Ruby.

Add in PHP, and that's increasingly impressive, but it does beg the question: Do we really need another all-purpose IDE alongside Eclipse? Doesn't that just dissipate the effort? Answers on the back of a postcard. (Via Tim Bray.)
