1. I use Komodo for Perl and Ruby development. I wouldn't be caught dead without it - the dragon has saved my bacon so many times I've lost count.
2. I hope NetBeans survives - it's really a quality development environment. If there was a Perl on the JVM like there is Python and Ruby, I'd be using NetBeans.
3. Once a project gets to a certain size, a *standardized* IDE is a requirement. You flat out can't manage a big project without one, and if two programmers can't agree on the development environment, one of them shouldn't be on the project.
